This article is not intended as medical advice, and should not be taken as such. It is simply a compilation of notes from my research to better maintain the health of my own dogs, and is shared for informational purposes only. The idea is to be much better prepared when one does consult with a veterinarian. :)

It can be overwhelming to notice that your dog suffers from a severe illness, especially if the problem is internal and can’t be treated directly.

Kidney disease in dogs is the process of losing kidney functions over a period of time, in other words, your dog’s kidney will lose its ability to extract waste products from the blood;

However, kidney failure does not necessarily mean the inability to make urine; in fact, most dogs with kidney problems will produce large quantities of urine, but their body waste won’t be effectively removed.

Why low phosphorus food is important for dogs with kidney problems?

Healthy kidneys can remove extra phosphorus in the blood; on the other hand, if your dog is suffering from chronic kidney disease, its kidney will not effectively remove phosphorus.

High levels of phosphorus can cause severe illness and can damage your dog’s body; extra phosphorus makes the bones weaker by pulling calcium out of them; in addition, high levels of phosphorus and calcium lead to dangerous deposits in the blood vessels, eyes, lungs and heart.

Controlling phosphorus and calcium levels is vital for dogs with kidney problems; ignoring this and feeding your dog foods with high phosphorus levels will result in increased risk of heart attack, stroke, or death.
