Best Kidney Disease Diet for Dogs

Similar to humans, the dog’s body will build up waste toxins in the system that needs to be removed to avoid issues with illnesses.

Toxins are mostly purged from the body via the kidneys, which helps to filter the waste and leaves the body through urine.

A normal kidney is able to remove a lot of daily toxins in a small amount of urine. But, the body doesn’t work so efficiently when a kidney starts to fail or is diseased.

A dog with kidney failure will attempt to drink more water to help the failing kidneys. After a time, the toxin levels in the body get too high and this can lead to death. Some of the signs of kidney failure include vomiting, weight loss, decreased appetite, and lethargy.

Kidney disease will progress in several different stages with the early difficulties noticeably different to what is expected when the disease progresses.

The right diet for a dog with kidney disease will depend on the stage of the disease. A preferred diet should match the specific stage of the condition.

A diet in the early stages shouldn’t be too limited because this can cause issues with muscle loss and protein undernourishment. But, as the health condition starts to deteriorate, a pet owner should look at changing the everyday diet to include certain modifications. 

 It is generally best to get guidance from the local vet to help improve the level of comfort and overall life expectancy. Generally best to get guidance from the local vet to help improve the level of comfort and overall life expectancy.

Hello, my name is Angela Miller. Several years ago, I rescued a little seven-year-old Bichon Frise. I started looking into dog nutrition so I could keep my little love bug for as long as I possibly could. I love my dog too much to feed him unhealthy food. I hope some of the things I've learned along the way will help you and your dog.
