Excess protein in the urine of dogs can either be an abnormality that is easily remedied by dietary changes, or it can be a condition called proteinuria, which is a sign of diseases or medical conditions that can be quite serious. Sometims dogs that suffer from proteinuria show no symptoms, which is why the condition is often found through routine urinalysis at regular vet visits. It’s normal for dogs to have some protein in their urine, but in the case of proteinuria, protein becomes too large and too high in quantity to be filtered by the kidneys. This often happens gradually in older dogs, but it can also be the result of kidney disease or other medical issues. If your veterinarian finds excess protein in your dog’s urine, it is important that they determine the underlying cause and treat the issue. Here is what you should know about the symptoms, causes, and treatments for excess protein in dogs’ urine.
