Ketone In Your Dog Or Cat’s Urine = Ketonuria

Most of the thin in-office test strips that veterinarians use to analize a sample of your pet’s urine contain a portion that changes color when ketones are present. There should not be any. When there is, it is usually evidence that your pet is burning its stored fat for energy instead of glucose sugar. That often occurs when pets refuse to eat, or when diabetes prevents them from utilizing their blood sugar properly.



Reasons Why Your Pet Might Have Ketone (ketone bodies, ketosis) In Its Urine :

Unmedicated or poorly controlled diabetes in dogs and cats, malnutrition and starvation are the most common causes.

Of course, any disease that prevents or makes pets uninterested in eating; particularly it is young and its nutritional demands for growth are high, will also "throw" them into ketosis (ketoacidosis).

Occasional, false-positive test results do occur. But those are usually low or borderline-positive color changes on the urine test strips.

Complementary Tests :

A urine and blood BHB (ß-Hydroxybutyrate) assay to confirm the positive urine ketone result, CBC/WBC and blood chemistry panels and then secondary tests depending on those results.
