Breeds documented: 1

Overview

With chronic kidney disease, the kidneys gradually lose their ability to do their usual work. They may struggle to remove waste and keep water, minerals and blood pressure in balance. The damage can have several causes and usually progresses over time. Early disease may cause few visible changes, while later disease can lead to increased thirst, weight loss and vomiting.

Signs to watch for

Drinking more water than usual
Passing urine more often or in larger amounts
Losing weight or showing less interest in food
Vomiting or diarrhea
Having less energy

More common in older dogs, although inherited forms can cause signs before three years of age.

When to get help Arrange a vet visit for increased thirst, changes in urination, weight loss or vomiting.

Diagnosis and tests

Vets combine blood and urine tests with an examination to assess kidney function. They may also measure blood pressure, culture urine for infection and use X-rays or ultrasound. The findings help establish the disease stage and guide treatment. Repeated testing helps track changes over time.
