What is kidney failure in dogs?
The kidneys play a vital role in filtering waste, regulating electrolytes, and maintaining hydration. Kidney failure (also called renal failure) happens when these organs lose their ability to function properly.
There are two types:
- Acute kidney failure – Rapid onset, often reversible if caught early
- Chronic kidney failure (CKD) – Progressive, common in senior dogs, and often irreversible
Early detection and supportive care can slow the progression of chronic kidney failure and improve quality of life.
Common signs of kidney failure in dogs
Recognizing early symptoms can lead to better outcomes. Watch for:
- Increased thirst and urination
- Decreased appetite
- Nausea or vomiting
- Weight loss and muscle wasting
- Lethargy or depression
- Bad breath with a chemical (uremic) smell
- Pale gums or mouth ulcers
- Poor coat condition
These symptoms may appear gradually in chronic kidney failure, or suddenly in acute cases.
How is kidney failure diagnosed?
If you suspect something’s wrong, your veterinarian will perform:
- Blood tests – To measure kidney function (BUN, creatinine, SDMA)
- Urinalysis – To evaluate urine concentration and protein levels
- Blood pressure measurement – High blood pressure is common in dogs with kidney disease
- Ultrasound or X-rays – To assess kidney size and structure
Early diagnosis gives your dog the best chance for stabilization and comfort.
Treatment and management
While kidney damage is often permanent, supportive care can reduce symptoms and prolong life.
1. Fluid therapy
- Subcutaneous or intravenous fluids help flush toxins and prevent dehydration.
2. Dietary changes
- Prescription renal diets are low in phosphorus, protein, and sodium.
- These help reduce the workload on the kidneys and slow progression.
3. Medications
- Anti-nausea drugs, phosphate binders, appetite stimulants, and blood pressure medications may be used.
4. Supplements
- Omega-3 fatty acids, potassium, and B vitamins may be recommended to support kidney function.
Regular vet visits and lab monitoring are crucial to adjusting the care plan as the disease evolves.
Home care and quality of life
Caring for a dog with kidney failure at home requires patience and consistency. Here are ways to help:
- Encourage water intake with clean, fresh water at all times
- Feed renal-friendly diets and limit treats high in protein or salt
- Administer medications and fluids as directed
- Create a calm, low-stress environment
- Watch for signs of pain, nausea, or worsening symptoms
While managing kidney failure is demanding, many dogs continue to enjoy life with proper care and support.
Understanding prognosis
The life expectancy of a dog with kidney failure varies. Some dogs live months or even years with chronic kidney disease, while others may decline quickly.
Factors that affect prognosis include:
- Stage of kidney disease (determined by bloodwork)
- Response to treatment
- Presence of other health conditions
- Age and overall vitality
Your veterinarian can help guide realistic expectations and plan for both medical care and comfort.
When it’s time to say goodbye
Despite your best efforts, there may come a point when treatment no longer helps and your dog is suffering. Signs that the end may be near include:
- Refusing food or water
- Severe lethargy or confusion
- Incontinence
- Difficulty standing or walking
- Labored breathing
- Pain or vocalization
Choosing euthanasia is one of the hardest decisions a pet owner will face — but it can also be the most compassionate.
Discuss options with your vet, including in-home euthanasia, so your dog can pass peacefully and without fear.
Memorializing your pet
After your dog passes, consider ways to honor their memory:
- Create a photo album or memorial shelf
- Plant a tree in their name
- Donate to a shelter or rescue in their honor
- Have their ashes placed in a keepsake urn
- Write about their life and your bond
These small acts can help with grief and provide comfort in the days ahead.
