Acute Kidney Failure in Dogs

Your dog’s healthy kidneys perform many vital functions. But dogs suffering from acute kidney failure may experience sudden, rapid decline in kidney function that will need urgent veterinary care. Here, our Greensboro vets list signs of acute kidney failure in dogs, and what to do if your dog displays symptoms.

Kidney Failure in Dogs

Kidney failure in dogs is also known as renal failure and may be caused by many diseases that impact how your pup’s kidneys function.

In healthy dogs, kidneys play a pivotal role in regulating hydration, removing toxins from the body, releasing hormones needed to produce red blood cells and maintaining a normal electrolyte balance. By contrast, dogs diagnosed with kidney failure no longer have kidneys that function efficiently. The two different kinds of kidney failure that appear in dogs are chronic kidney failure and acute kidney failure.

Causes of Acute Kidney Failure in Dogs

Within hours or days of the triggering incident, kidney function may suddenly decrease. This is referred to as acute kidney failure and is most often associated with toxins or infections.

Acute kidney failure in dogs can be caused by the bacterial infection leptospirosis (which is contracted by ingesting contaminated water) or dehydration. Other causes include the ingestion of:

  • Ibuprofen
  • Grapes and raisins (alone or in other foods)
  • Antifreeze (often licked from a garage floor or driveway)
  • Human heart medications
  • Overdose of canine medications such as nonsteroidal anti-inflammatory drugs (NSAIDs)

Symptoms of Acute Kidney Failure

Signs of acute kidney failure in dogs will appear quickly, usually within a couple of hours or days of ingesting the toxin. You may notice one or more of these symptoms if your dog is suffering from acute kidney failure:

  • Vomiting
  • Lethargy
  • Increase or decrease in water consumption
  • Ulcers in the mouth
  • Increase or decrease in volume of urine
  • Uncoordinated movement such as stumbling
  • Significant decrease in appetite
  • Breath that smells like chemicals

Diagnosing Acute Kidney Disease in Dogs

Your vet will run a series of blood and urine tests to confirm that your pup is suffering from kidney failure and to get a complete picture of the extent of the disease. Radiographs (X-Rays), ultrasound, blood tests, and urinalysis are typically used when diagnosing acute kidney failure. The results of these tests will also provide your vet with a more complete picture regarding the extent of the condition. In some cases, a biopsy of the kidney may also be recommended.

Treatment for Acute Kidney Failure in Dogs

Acute renal failure is a very serious health risk for dogs. Hospitalization and intensive care may be required to save your pup's life. Staff at our clinic will very closely monitor your dog's heart rate, blood pressure, and overall condition while providing appropriate medications and treatments such as IV fluids to hydrate and flush out the kidneys. Once IV fluids have been administered your veterinary team will monitor your pet's urine production for signs of improvement.

Kidney Dialysis (Hemodialysis)

Peritoneal dialysis (feeding a tube directly into the pet's stomach to supply fluids which will be removed after some time to help flush out toxins) may be required.

Antibiotics may be administered if the cause of your dog's kidney failure is an infection. Medications may be given to prevent or treat stomach ulcers (which are a common side effect of acute kidney failure).

In some cases, a feeding tube may be needed until your dog is feeling better and able to eat on their own.

Can dogs survive acute kidney failure?

This condition is very serious and sadly the prognosis for dogs suffering from acute kidney failure is poor. It is estimated that more than half of pets suffering from acute kidney failure either die from the condition or are euthanized to prevent suffering.

That said, if caught early and treated aggressively some dogs are able to recover from acute kidney failure.

Your vet will be able to provide you with a realistic prognosis for your pet's recovery following a complete examination and testing. Your veterinarian will provide you with an estimate of treatment costs and help to guide you through the most appropriate approach to treatment for your pup.

  • For 10+ years now, the fine folks at Friendly Animal Clinic have provided top-notch care and boarding to my unruly, little band of kitty hooligans. They've been great with my babies, the stray-bies I've dragged in and even helped with reuniting a few lost souls with their owners. They care a great deal about their patients (and the humans who accompany them) and it shows...from the front desk staff to the vet techs/assistants to the doctors.
