Kidney & Liver Problems in Dogs and Cats: Early Symptoms & Care

Pets cannot tell us when something feels wrong. That’s why understanding Kidney & Liver Problems in Dogs and Cats is essential for every responsible pet parent. The kidneys and liver are two of the most important organs in your pet’s body. When they fail to function properly, it can quickly become life-threatening.

Early detection, proper care, and timely veterinary support can significantly improve your pet’s quality of life. In this guide, we’ll explain the early symptoms, causes, diagnosis, treatment, and preventive care for Kidney & Liver Problems in Dogs and Cats.

Why Are Kidneys and Liver Important?

Before understanding Kidney & Liver Problems in Dogs and Cats, it’s important to know what these organs do.

Kidney Function

• Filters waste products from the blood

• Maintains water balance

• Regulates electrolytes

• Produces essential hormones

Liver Function

• Detoxifies harmful substances

• Produces bile for digestion

• Stores nutrients and vitamins

• Supports metabolism

When either organ begins to fail, toxins build up in the body, affecting multiple systems.
