What is kidney failure in dogs?


Your dog’s kidneys are important because they remove waste substances from the bloodstream and maintain the normal balance of fluid and minerals within the body. But if the kidneys are not able to do their job, the result could be life threatening for your dog.

Kidney failure is a condition that damages your dog’s kidneys, leading to kidney or renal disease. The most common and widespread form of kidney failure in dogs is called Chronic Kidney Disease (CKD).

Early detection of kidney failure in your dog

In some cases, dogs may show early warning signs of kidney disease. However, signs of serious illness only appear after 75% of kidney function has already been lost. This is the reason why early detection of renal failure in your dog is so important.


The sooner kidney disease is diagnosed, the more time there is to address the underlying cause or slow the disease’s progression. On diagnosis, the condition has already been present for some time, but this lifelong disease can be managed very well with the right nutrition.


IMPORTANT: An increase in thirst may be the first sign of kidney failure. If you notice this, or any of the signs below, consult your veterinarian immediately.

How can the right food help?


The food your dog eats plays an important role in his overall health and well-being. Specially formulated foods for dogs with kidney failure concerns can be beneficial by having less protein and phosphorous than other pet foods. Phosphorus restriction can lessen the severity of the symptoms and progression of kidney damage, while decreased, high-quality proteins can help restore normal acid-base levels.

If your dog has kidney disorders the right nutrition may be able to make a positive impact on her life and potentially even lengthen her lifespan. Consult with your veterinarian and discuss the best food for your dog’s kidney health.
