What is Kidney Failure in Dogs?
Kidney failure in dogs is a serious clinical condition that results from the kidneys' inability to perform their basic functions. Normally, the kidneys filter toxins and waste products from the body, regulate water and electrolyte balance, produce hormones that control blood pressure, and support red blood cell production. However, when kidney tissue is damaged, these vital functions are disrupted, and the body rapidly becomes overwhelmed with toxic substances.
Kidney failure occurs in two main forms: acute renal failure (AKI) and chronic renal failure (CKD) . In the acute form, kidney function deteriorates suddenly over a short period of time, often within days or weeks. In the chronic form, the kidneys gradually lose function over months or years. While both forms can have serious clinical consequences, their causes, symptoms, and treatment approaches differ.
When kidney tissue is damaged, waste products such as urea, creatinine, and phosphorus begin to accumulate in the body. This leads to common symptoms such as loss of appetite, vomiting , weakness, dehydration, and weight loss. Urinary output can also vary; some dogs experience excessive urine production, while others barely urinate at all. As kidney function deteriorates, water-salt balance becomes disrupted, blood pressure rises, and anemia can develop.
Kidney failure in dogs can quickly lead to serious complications if not detected early. Therefore, early diagnosis, accurate laboratory tests, and an appropriate treatment plan are crucial.
Differences Between Acute and Chronic Kidney Failure in Dogs
Acute (AKI) and chronic (CKD) forms of kidney failure in dogs have distinct clinical courses. Understanding these differences is critical for selecting the appropriate treatment plan.
Acute renal failure occurs when the kidneys lose function over a very short period of time. It usually develops due to toxin ingestion, severe infections (e.g., leptospirosis), renal vascular occlusion, sudden dehydration, heat stroke, or trauma. This condition sometimes progresses within hours or a few days. The most significant advantage of the acute form is that with early intervention, kidney function can be fully restored. Therefore, prompt diagnosis and treatment are extremely critical.
Chronic kidney failure, on the other hand, is a condition that progresses slowly over months or years. Kidney tissue is irreversibly destroyed. This can be caused by factors such as aging, genetic predisposition, immune system diseases, long-term hypertension, or chronic inflammation. In the chronic form, kidney tissue does not regenerate; however, the disease can be stable for long periods, and with proper care, the dog can live a quality life.
In the acute form, symptoms begin suddenly: loss of appetite, vomiting, inability to urinate, sudden weakness, intense thirst, or, conversely, complete lack of water intake are common. In the chronic form, symptoms are milder and worsen over time: weight loss, bad breath, dull fur, increased water consumption, frequent urination, and occasional nausea.
In terms of treatment, the acute form generally requires intensive fluid resuscitation, detoxification, and immediate supportive care, while the chronic form emphasizes long-term management, a renal diet, medications, and regular blood checks. Consequently, distinguishing between the two forms is crucial for both prognosis and treatment options.
Causes of Kidney Failure in Dogs (Infections, Toxins, Genetic Factors)
There are many different causes of kidney failure in dogs, and these causes are generally rooted in sudden or prolonged damage to the kidney tissue. Kidney tissue is extremely sensitive; changes in blood flow, toxins, infections, and genetic predisposition can rapidly affect kidney function. Therefore, accurately understanding the causes of kidney failure is critical for both diagnosis and treatment planning.
1. Infections (Leptospirosis, Pyelonephritis, Viral Diseases) Bacterial infections are among the most serious causes of kidney failure. Leptospirosis , in particular, is one of the most significant infections causing acute kidney failure in dogs. After entering the body, Leptospira bacteria can colonize the kidney tissue, causing severe inflammation, cell destruction, and sudden loss of function. Another important infection is pyelonephritis , an inflammation of the kidneys. This condition usually occurs when lower urinary tract infections progress upward. If left untreated, it can cause permanent damage to kidney tissue.
2. Toxic Substances (Grapes, Lilies, Antifreeze, Painkillers) One of the fastest developing causes of kidney failure in dogs is toxic substances.
Antifreeze (ethylene glycol) poisoning can lead to fatal acute renal failure within hours.
Grapes and raisins can cause serious damage to kidney cells in dogs, and although the exact mechanism of action is unknown, even small amounts are dangerous.
Lily flowers can be risky for dogs as well as cats.
NSAID group painkillers (such as ibuprofen, naproxen) can cause serious damage by disrupting kidney blood flow.
Disinfectants, heavy metals, poisonous mushrooms, and some cleaning agents can also damage kidney tissue.
3. Genetic and Breed Predisposition: Kidney disease is more common in certain dog breeds. For example, Shar Pei, Basenji, Shih Tzu, Cocker Spaniel, and Retriever breeds are more likely to have glomerular disease, congenital kidney malformations, or immune-mediated kidney diseases. This can lead to the gradual deterioration of kidney tissue over time.
4. Age-Related Changes (Chronic Degeneration) As dogs age, their kidney tubules, glomeruli, and blood vessels naturally weaken. This process can lead to slowly but steadily progressing chronic kidney failure, especially in dogs over 7 years of age. While this is a completely natural aging process, it can be managed long-term with early diagnosis.
5. Low Blood Pressure and Dehydration. A sudden drop in blood pressure (trauma, blood loss, sudden infections) reduces blood flow to the kidneys, and kidney cells are starved of oxygen and die rapidly. Similarly, severe dehydration can quickly impair kidney function.
6. Immune System Diseases: In some dogs, the immune system can attack the glomeruli, the filtering units of the kidneys, causing a condition called glomerulonephritis . This can lead to chronic kidney failure in the long term.
In conclusion, kidney failure isn't caused by a single cause; it's a combination of environmental, genetic, and clinical factors. Therefore, knowing these risk factors is crucial for protecting your dog's health.

May predispose to immune-mediated kidney diseases | Middle | |
An increased risk of chronic kidney disease has been clinically observed | Middle | |
Kidney stones and chronic kidney disease are more common | Middle | |
basenji | Carries a genetic predisposition to severe kidney disease known as Fanconi syndrome | A lot |
Symptoms of Kidney Failure in Dogs
The symptoms of kidney failure in dogs vary depending on whether the disease is acute (sudden onset) or chronic (slowly progressing). However, in both forms, toxic substances begin to accumulate in the body due to the kidneys' diminished filtering capacity, leading to a variety of behavioral, digestive, and systemic symptoms. Early detection of symptoms significantly increases treatment success.
1. Increased water drinking and frequent urination (polydipsia–polyuria). As kidney function begins to deteriorate, dogs will drink more water and urinate more frequently. This is one of the earliest and most obvious signs of chronic kidney disease. Some owners first notice their dog's water bowl running out quickly or constantly wanting to go outside.
2. Loss of appetite and weight loss. The accumulation of toxins in the blood causes nausea and loss of appetite. The dog doesn't consume its normal portions, and over time, noticeable weight loss occurs. This symptom is more pronounced in chronic disease.
3. Weakness and depressive behavior. Waste products accumulating in the bloodstream rapidly reduce a dog's energy levels. The dog sleeps more, loses interest in walking, and is less interested in its surroundings. This can occur in both acute and chronic forms of kidney failure.
4. Vomiting and Nausea. Increased urea and toxins can affect the stomach wall, causing frequent vomiting. In advanced cases, the vomit may be brownish in color and may be tinged with blood.
5. Bad Breath (Uremic Odor) When kidney function is severely impaired, substances accumulate in the blood, creating a chemical odor in the mouth. This odor has been described as ammonia-like, metallic, or "medicine-like."
6. Dehydration and dry mucous membranes: When the kidneys can no longer retain water, the dog loses fluid rapidly. Loss of skin elasticity, a dry nose, and a dry mouth are typical signs of dehydration.
7. Anemia and pale gums: The kidneys produce the hormone erythropoietin, which stimulates red blood cell production. As kidney failure progresses, this hormone decreases, and anemia develops. This condition manifests as weakness, easy fatigability, and pale gums.
8. Neurological symptoms: In the later stages of the disease, incoordination, tremors, seizures, and behavioral changes may occur due to the effects of toxic substances on the brain. This is a critical stage.
9. Mouth sores (Uremic ulcers) In chronic cases, sores, ulcers, and canker sores-like lesions may occur in the mouth. This indicates that the urea level in the blood is too high.
10. Decreased urine output (oliguria) or an inability to urinate (anuria) is one of the most dangerous stages of acute kidney failure. When a dog can't produce urine, toxins accumulate rapidly, making the situation life-threatening.
Although these symptoms alone do not definitively indicate kidney failure, veterinary evaluation is absolutely necessary, especially when increased water consumption and loss of appetite occur together.
Diagnosis of Kidney Failure in Dogs (Blood Test, Urinalysis, Imaging)
Kidney failure cannot be diagnosed solely by symptoms; a definitive diagnosis can only be made through a combination of laboratory tests and imaging studies. This is because noticeable symptoms only appear when the kidney tissue is 60–70% damaged, and early diagnosis is crucial at this stage.
1. Blood Test (BUN, Creatinine, SDMA, Phosphorus) The most important tests in evaluating kidney functions are blood biochemistry.
Urea (BUN) : If it is elevated, the filtering capacity of the kidney is reduced.
Creatinine : It is one of the most reliable indicators of kidney dysfunction.
SDMA : It is the earliest biomarker to detect kidney damage; it rises long before creatinine.
Phosphorus : Increases in chronic kidney disease and disrupts the mineral balance in the body.
2. Urine Analysis (USG, Proteinuria, Sediment Examination) The density of the urine (USG) shows how much water the kidneys filter.
Low density (hyposthenuria) indicates that the kidneys are unable to retain water.
Proteinuria (protein in the urine) is an important indicator of glomerular damage.
Increased bacteria, crystals, or cells in the urine sediment may suggest kidney infections.
3. Blood Pressure Measurement: Hypertension is both a cause and a consequence of kidney failure. Dogs with high blood pressure can quickly develop damage to their kidneys and eye vessels.
4. Ultrasonography In kidney failure, ultrasound is the most commonly used method to evaluate the size, shape, texture, and blood flow of the kidneys.
In acute failure, the kidneys may be swollen and tender.
In chronic failure, the kidneys appear shrunken, their surface rough, and their tissue thin.
5. Radiography (X-ray) It is used to evaluate kidney dimensions, detect the presence of stones and identify some anatomical disorders.
6. Advanced Tests (PCR, Kidney Biopsy) In rare cases, a biopsy may be required to determine the source of infection or confirm a specific kidney disease. PCR tests can be useful in the diagnosis of infections such as leptospirosis.
Accurate diagnosis is the most crucial factor in determining the success of a treatment plan. Early detection of kidney failure, especially in its chronic form, can be managed for years.
Treatment Methods for Acute and Chronic Renal Failure in Dogs
Treatment of kidney failure in dogs varies greatly depending on whether the disease is acute (sudden onset) or chronic (progressive over time). The acute form requires immediate and intensive intervention, while the chronic form can be managed with long-term management and lifestyle changes. In both cases, the goals of treatment are to support kidney function, reduce toxin accumulation, and prevent complications.
Treatment of Acute Kidney Failure
Because acute renal failure (AKI) can develop over hours or days, rapid intervention is lifesaving. Treatment is usually provided in a hospital setting, with intensive clinical support.
1. Fluid therapy (administration via IV cannula) Rapid correction of dehydration, regulation of blood circulation, and increased blood flow to the kidneys are the foundation of treatment. Intravenous fluids accelerate the elimination of toxins from the body.
2. Removal of toxins If there are causes such as antifreeze (ethylene glycol), grape/chocolate toxicity or drug poisoning, special antidotes or detox protocols are applied.
3. Monitoring urine output: Oliguria (little urine) and anuria (no urine at all) are dangerous. In these cases:
Diuretics (e.g., furosemide)
Catheterization
If necessary, dialysis (hemoperfusion or peritoneal dialysis) can be performed.
4. Treatment of infection: Antibiotic treatment is essential in cases of infection-related infections such as leptospirosis. Early initiation of this treatment can prevent permanent damage to the kidney tissue.
5. Correction of electrolyte and acid-base balance If values such as potassium, sodium and bicarbonate are irregular, they are corrected clinically.
The most significant advantage of acute kidney failure is that with prompt and appropriate treatment, kidney function can be fully restored. However, any delay may lead to permanent damage.
Treatment of Chronic Kidney Failure
Chronic kidney disease (CKD) is a slowly progressive, irreversible condition. Treatment is focused on managing the disease and slowing its progression , not "fixing the damage."
1. Renal (kidney-friendly) diets: Medical renal formulas contain low phosphorus, controlled protein, and an ideal balance of omega-3s. These formulas reduce kidney burden and prolong life.
2. Blood pressure control Hypertension damages kidney tissue more quickly.
Amlodipine
ACE inhibitors (e.g., benazepril, enalapril) are frequently used.
3. Phosphorus binders: If blood phosphorus levels are elevated, phosphorus binders added to food are used. These products reduce kidney burden by blocking the absorption of phosphorus from food.
4. Nausea and gastric protection treatments Vomiting and nausea are common in chronic patients:
Antiemetics (maropitant, onasetron)
Antacids (famotidine, omeprazole) can be used.
5. Fluid support (at home or in the clinic) For some chronically ill patients, periodic subcutaneous fluid administration is recommended. This method reduces toxin buildup and increases the dog's energy level.
6. Anemia treatment: Anemia may develop in patients with chronic kidney disease due to decreased erythropoietin. B12 supplements, iron supplements, or erythropoietin analogs may be used if necessary.
When chronic kidney failure is well managed, dogs can live a long and quality life.
Complications and Prognosis of Kidney Failure
Kidney failure can lead to numerous complications, both acute and chronic. These complications directly impact the course of the disease, treatment, and quality of life.
Possible Complications
1. Uremic syndrome: When urea and toxins in the blood rise to dangerous levels, vomiting, mouth sores, bad breath, neurological disorders and severe weakness occur.
2. Hypertension (high blood pressure) As kidney vessels become damaged, blood pressure rises. This can lead to damage to the eye vessels and the brain.
3. Electrolyte disturbances: High potassium levels (hyperkalemia) can cause fatal arrhythmias. Sodium imbalance can cause nervous system symptoms.
4. Anemia: As the erythropoietin hormone decreases, dogs tire easily, become lethargic and have pale mucous membranes.
5. Dehydration and low blood pressure Chronic dehydration can lead to serious organ damage because the kidneys cannot retain water.
6. Heart and lung effects: In advanced kidney failure, toxins can affect the heart muscle and respiratory system, causing rhythm disturbances and breathing difficulties.
Prognosis (Life Expectancy and Recovery Status)
Acute renal failure: If treated early, recovery is possible. However, if treatment is delayed, the prognosis is more cautious. The risk of death is higher in toxin-induced cases.
Chronic renal failure: This is an irreversible condition, but it can be kept stable for years . Quality of life can be significantly improved with a renal diet, regular checkups, and medications.
Prognosis varies depending on the stage of the disease, the age of the dog, the source of infection, blood values, and the regularity of treatment.
Home Care, Nutrition and Supportive Treatments (Renal Diet, Fluid Therapy, Supplements)
One of the most critical aspects of canine kidney failure treatment is home care protocols. Veterinary clinical treatment manages the acute phase of the disease, but long-term success depends largely on regular home care, proper nutrition, and supportive therapies. The goal of home care is to reduce kidney burden, slow toxin accumulation, and maintain a high long-term quality of life.
1. Renal (Kidney-Friendly) Diets
Renal formulas are the cornerstone of chronic kidney disease management. These formulas:
Contains low phosphorus (reduces kidney load),
Provides high quality but limited protein (reduces toxin production),
Rich in omega-3 fatty acids (reduces inflammation),
Potassium, sodium and B vitamins are balanced.
Home-cooked meals are not suitable for kidney disease. Feeding your dog homemade food can lead to uncontrolled phosphorus and protein intake, rapidly worsening the disease.
2. Home Fluid Support
One of the most common problems in chronic kidney disease is dehydration . Even if a dog drinks enough water, the kidneys can't reabsorb it, causing the body's fluid levels to drop.
In this situation:
Subcutaneous fluid administration at home (administering fluid under the skin)
Regular IV fluid support is used in the clinic. Home fluid administration can be taught to dog owners under veterinary supervision and significantly prolongs the lifespan of chronically ill patients.
3. Supplements (Veterinarian Approved)
Some supplements are very beneficial for kidney patients:
Omega-3 fatty acids: Reduce inflammation and support kidney function.
Vitamin B12: It is beneficial for decreased appetite and anemia in kidney patients.
Potassium supplements: May be necessary if blood potassium is low (hypokalemia).
Phosphorus binders: They prevent phosphorus in foods from passing into the body.
Probiotics (nitrogen-fixing bacteria): Helps to remove urea through the intestines.
It is very important that every supplement is given with veterinary approval; the wrong supplements can put even more strain on the kidneys.
4. Special Nutrition and Lifestyle
Your dog:
Salt-free diet,
Keeping away from fatty and processed foods,
24-hour access to fresh water,
Avoid excessive exercise,
Living in a calm environment, away from stress, has a positive effect on kidney functions.
In dogs with kidney disease, regular blood checks (SDMA, creatinine, phosphorus) and urinalysis are an integral part of long-term management.
What Owners Need to Know and Long-Term Management
Kidney failure is a chronic disease and often goes untreated; however, with proper care, a dog can live a quality life for many years. It's crucial for dog owners to be aware of this and plan their household management effectively.
1. Regular Veterinary Checkups
For dogs with chronic renal failure:
Blood tests every 1–3 months,
Urine test every 3–6 months,
Regular blood pressure measurement is required.
Thanks to these follow-ups, changes in kidney function are detected early.
2. Regular Use of Medications
Missing ACE inhibitors, antiemetics, blood pressure medications, or phosphorus binders can cause rapid worsening of the condition. These medications should be given at the same time each day .
3. Recognizing Early Warning Signs
Owners should contact their veterinarian immediately if they notice the following symptoms:
Sudden increase or decrease in water consumption
Vomiting
Significant worsening of bad breath
Loss of appetite
Extreme fatigue
Change in urine output
These symptoms may indicate worsening kidney function.
4. Organizing the Home Environment
Dogs with chronic renal failure:
Being sensitive to cold,
Experiencing sudden energy drops,
It is normal for him to become more mentally sensitive.
Therefore, it is important to create a calm, low-stress living space.
5. Nutritional Discipline
The most common mistake owners make is the tendency to give their dogs treats, home-cooked meals, or table food. A renal diet is only suitable for kidney patients. Even small deviations can be harmful by increasing kidney load.
6. Quality of Life Monitoring
Quality of life in dogs is assessed by appetite, daily activity level, drinking habits, sleep, stool and urine patterns, and daily cheerful behavior. Owners should monitor these parameters and report them regularly to their veterinarian.
When chronic kidney disease is managed properly, dogs can live active, happy, and comfortable lives for many years. An informed approach from owners is the most powerful tool in treatment.
Differences Between Kidney Failure in Dogs and Cats
Kidney failure is a serious clinical condition that can occur in both dogs and cats; however, there are significant differences between the two species in terms of disease progression, signs, rate of progression, and response to treatment. Recognizing these differences is particularly important when both species live in the same household, as each has different clinical management.
1. Frequency of Disease Incidence
Chronic kidney disease ( CKD ) is much more common in cats than in dogs. While it's particularly common in cats over 8 years of age, chronic kidney disease occurs less frequently in dogs. Cats' natural physiology and kidney structure make them more prone to loss of function with age.
Acute renal failure ( AKI ) is seen in both dogs and cats; however, AKI is more common in dogs because dogs are more prone to ingesting toxic substances (grapes, antifreeze, medications).
2. Speed of Onset of Symptoms
Cats are very good at hiding their illnesses. This is why kidney failure in cats is often detected at a very advanced stage. In dogs, however, the symptoms (increased water drinking, increased urination, weakness) are noticed earlier, and owners are more likely to seek veterinary care.
3. Water Consumption and Urinary Pattern
In cats with chronic renal failure:
Water consumption increases significantly,
Dehydration may occur despite drinking plenty of water,
Frequent urination is very common.
Although similar signs are seen in dogs, dogs respond more quickly to clinical changes.
4. Nutritional Differences
Renal diets are the mainstay of treatment for both types, but:
Cats do not respond as well to protein restriction as dogs because they are obligate carnivores.
While more aggressive protein and phosphorus restriction can be applied in dogs, this limit is more flexible in cats.
5. Response to Treatment
Chronic renal failure in cats is usually irreversible, but it can be very well managed and kept stable for long periods. In dogs, the likelihood of full return of kidney function is higher, especially in acute forms.
6. Life Expectancy and Prognosis
CKD in cats is a long-term condition, and most cats can live stable for many years. In dogs, the prognosis varies depending on the type of disease:
Rapid intervention is very important in acute renal failure.
The chronic form can progress if not managed well.
7. Distribution of Causative Factors
In dogs, toxin ingestion and infections (especially leptospirosis) are the most important causes.
Aging, chronic urinary tract problems, and stone formation are more common in cats.
In conclusion, the two types of kidney failure have different physiological basis, clinical course, and treatment requirements. Therefore, treatment and care plans must be tailored to each type.
Frequently Asked Questions (FAQ)
What exactly is kidney failure in dogs and how does it develop?
Kidney failure in dogs is a serious clinical condition caused by the accumulation of toxins in the body due to the kidneys' inability to filter blood. This condition can develop acutely (suddenly onset) or chronically (slowly progressing). The acute form develops rapidly due to toxins, infections, or a sudden drop in blood pressure, while the chronic form develops gradually due to genetic predisposition, aging, or long-term kidney damage.
How to recognize early signs of kidney failure in dogs?
Early symptoms often include increased water consumption, frequent urination, loss of appetite, weakness, and weight loss. While these symptoms are often perceived as "normal changes" by owners, they are often the first warning signs of kidney failure in dogs.
How does kidney failure in dogs differ in acute and chronic form?
Acute kidney failure develops rapidly, with severe symptoms appearing within hours or days. Chronic kidney failure progresses over months or years and is most common in older dogs. In the acute form, recovery is high; in the chronic form, the damage is irreversible but manageable.
What factors cause kidney failure in dogs?
Kidney failure in dogs can develop as a result of toxins (antifreeze, grapes, excessive painkiller use), infections (leptospirosis), genetic disorders, kidney inflammation, aging, low blood pressure, prolonged dehydration, or immune system diseases.
Which breeds are prone to kidney failure in dogs?
Kidney failure is more common in breeds such as Shar Pei, Cocker Spaniel, Shih Tzu, Basenji, Golden Retriever, and Labrador Retriever. These breeds are genetically predisposed and may develop kidney dysfunction at an earlier age.
Why does a dog with kidney failure drink a lot of water?
Because the kidneys are unable to reabsorb water, the dog must drink more. This is one of the earliest and most characteristic signs of kidney failure. It is also accompanied by frequent urination.
Does kidney failure in dogs cause loss of appetite and weight loss?
Yes. Toxin buildup causes nausea and loss of appetite. The dog refuses to eat, expends less energy, and experiences significant weight loss over time. This is particularly common in the chronic form.
How is kidney failure diagnosed in dogs?
Definitive diagnosis is made through blood tests (BUN, creatinine, SDMA, phosphorus), urinalysis (USG, proteinuria), and imaging methods such as ultrasound. In the early stages, the SDMA test is a much more sensitive marker than creatinine.
Why is ultrasound important in kidney failure in dogs?
Ultrasound reveals structural changes in the kidneys, including shrinkage or swelling, and textural differences. In acute damage, the kidneys may be swollen, while in chronic disease, they appear shrunken and have a rough surface.
Can kidney failure in dogs be treated?
Acute kidney failure can be completely cured if treated promptly. Chronic kidney failure, however, is irreversible but can be kept stable for many years with proper nutrition, medications, and regular monitoring.
How long can a dog with canine kidney failure live?
The answer to this question depends on the stage of the disease, the dog's age, and its response to treatment. With proper care, dogs with chronic kidney disease can live many years with quality of life. In the acute form, early intervention is crucial.
What are the most effective treatments for kidney failure in dogs?
IV fluid therapy, renal diet, blood pressure regulating drugs, phosphorus binders, antiemetics, subcutaneous fluid administration and antibiotic therapy when necessary are among the most effective methods.
Is dialysis necessary for kidney failure in dogs?
In severe cases of acute kidney failure, when urine production stops, dialysis can be lifesaving. In certain cases of chronic kidney failure, it can be used to lower toxin levels.
What should a dog with kidney failure eat?
The most appropriate diet for kidney failure is renal formulas. These formulas contain low phosphorus, controlled protein, and omega-3 fatty acids. Homemade meals are definitely not recommended because their nutritional value is uncontrolled.
How to manage water consumption for kidney failure in dogs?
Water is not restricted. On the contrary, it is mandatory to have fresh water available 24 hours a day. Chronically ill patients may not be able to drink enough water, so subcutaneous fluid supplementation may be necessary.
Does kidney failure cause bad breath in dogs?
Yes. Uremic toxins cause a chemical, ammonia-like foul odor in the mouth. This symptom indicates that the disease is progressing.
Why is vomiting common in dogs with kidney failure?
The increase in urea and toxins in the bloodstream irritates the stomach. This leads to nausea and vomiting. Vomiting is more frequent in chronic cases and requires veterinary attention.
Does kidney failure cause anemia in dogs?
Yes. When the kidneys don't produce enough of the hormone erythropoietin, red blood cell production decreases. This leads to anemia, fatigue, and pale gums.
Can kidney failure in dogs lead to heart problems?
Yes. Electrolyte imbalances and hypertension can cause heart rhythm disturbances, weakness, and easy fatigue. In advanced cases, serious cardiac problems can develop.
How should dogs with kidney failure exercise?
Excessive fatigue puts more stress on the kidneys. Light walks and short activities are ideal. However, strenuous exercise, long runs, or activity in extremely hot weather are not recommended.
Can kidney failure in dogs be completely prevented?
Although it cannot be completely prevented, the risk can be greatly reduced by keeping away from toxins, doing regular blood checks, preventing tick-borne infections, and eating a healthy diet.
What happens if kidney failure in dogs is detected at a late stage?
In the late stage, symptoms become more severe: vomiting, dehydration, neurological signs, and bad breath may occur. In this case, urgent clinical support is required and the prognosis is more cautious.
How to improve the quality of life of dogs with kidney failure?
Renal diet, regular fluid support, appropriate exercise, stress reduction, regular tests, and regular medication follow-up greatly improve the quality of life.
Why is the difference between kidney failure in dogs and kidney failure in cats important?
Because treatment requirements, nutritional limits, and the rate of disease progression vary from species to species, dogs are more sensitive to toxins, while cats are more prone to chronic kidney disease.
When is urgent veterinary attention required for kidney failure in dogs?
If your dog is experiencing an inability to urinate, severe vomiting, extreme weakness, seizures, mouth sores, vomiting blood, pallor, severe dehydration or rapid deterioration, immediate emergency care is required.
