kidney failure dogs final stages

If your dog has been diagnosed with this renal disease or you're worried they're showing signs associated with end-stage kidney failure, a lot is probably going through your mind right now. At the forefront might be which stage of kidney disease does your dog fall under, and how can you make them as comfortable as possible? It's advisable to educate yourself about what to expect as your pet's illness progresses. That way, you can give them the best quality of life all the way through their final days.

Dog Kidney Failure Stages

Dogs with kidney failure go through a series of four stages, from diagnosis through the eventual death of the animal. These stages do not necessarily occur within rapid succession. A dog can go through them over the course of a few months or even years. Veterinarians determine the stage your dog is in by testing the urine to look for signs of the deterioration of the kidney's functions and the blood for symmetric dimethylarginine (SDMA) levels.

The Four Stages of Kidney Failure Chart

The canine kidney failure stages are determined by the levels of creatinine and SDMA, as well as the urine-to-protein (UPC) ratio and the animal's systolic blood pressure.

Other clinical indications that a dog is in the stages of kidney failure are:

• UPC Ratio:
  • Nonproteinuric: less than 0.2
  • Borderline proteinuric: 0.2 to 0.5
  • Proteinuric: greater than 0.5
• Systolic blood pressure (in mmHg):
  • Normotensive: less than 150
  • Borderline hypertensive: 150 to 159
  • Hypertensive: 160 to 179
  • Severely hypertensive: greater than 180

Symptoms of End-Stage Kidney Failure in Dogs

The most common signs a dog is dying from kidney failure include:

• Uremia: The buildup of waste products in the body produces a distinctive ammonia smell that is especially apparent on the breath.
• Pale, dry gums: The gums are duller and dry to the touch.
• Mouth ulcers: Uremia causes raw mouth ulcers that are painful.

Keeping Your Pet Comfortable

Watching your pet go through this can be very difficult. However, there are things you can do to help keep your dog comfortable during the final stages of kidney disease.

• Spend as much time as possible with your dog. Even being in the same room will be soothing to them.
• Make sure your dog's resting area is quiet, warm, and cozy. Provide them with their favorite blanket and toy.
• Protect your pet from other pets or people who may be too rough with them. Supervise interactions with children and teach them to be gentle with the dog.
• Pet your dog and talk to them frequently.
• Change your dog's bedding often and keep them clean and dry. Brush their fur for dry cleaning. Clean their fur with a sponge bath solution of hypoallergenic pet shampoo.
• Feed your pet a low-protein dog food appropriate for a kidney failure diet.
• If your dog refuses to eat or has trouble eating, ask the veterinarian about other feeding options such as an esophagostomy tube to keep them nourished.
• Monitor your dog's temperature and keep them warm with plenty of cozy blankets.

Last Days of a Dog Dying From Kidney Failure

While a dog owner may fear that entering the final stage of kidney failure means their dog's passing away is imminent, it is difficult to predict how long the does has left. In general, you can expect your dog to pass away within three months of moving into stage 4, though some dogs may thrive for up to a year.

It depends on the associated symptoms and other conditions that may arise due to the dog's poor health. Your dog's age is another factor. There's a lot to keep in mind, a lot to hope for, and the reality that you're facing the end of your dog's life.

Fast Fact

Controlling your dog's diet can help during their struggle with renal failure. Carefully discuss nutrition with your dog's veterinarian.

When to Consider Euthanization

When a dog enters end-stage renal failure, your veterinarian may recommend an end-of-life home treatment plan or a hospice program to make your pet's last days comfortable and maintain your pet's quality of life. For end-stage kidney failure, a treatment plan may include dialysis, a stomach tube, intravenous therapy, pain medication, and methods to care for an incontinent pet.

Depending on their symptoms, your dog may not necessarily be in severe pain, but they will be uncomfortable at the least from other symptoms, including frequent vomiting and diarrhea, lethargy and depression, and constant dehydration. Your veterinarian may recommend euthanasia if a dog is suffering, unresponsive to pain management, or too weak to handle necessary life-sustaining treatment.

Dealing With the Loss

It's hard to come to terms with the fact that a pet is dying. Find comfort in the fact that your dog appreciates your loving care in their final days. They know you love them and take comfort in your presence and all that you do to make their life easier.
