Diabetes in Dogs

Detection & Diagnosis

Attention to Details

No one knows your dog better than you do. Diabetes can cause visible changes in your dog’s behavior and health. It is important that your dog be thoroughly examined by a veterinarian at least once a year. For dogs as risk, more frequent visits may be advised.

A Visit to Your Veterinarian

If your dog shows signs of diabetes, your veterinarian will ask about them, and check your dog’s general health to rule out the possibility of other conditions or infections.

Your veterinarian will first test your dog for the presence of glucose and ketones in the urine. If indicated, the next step is to measure your dog’s blood glucose concentration. The diagnosis only becomes definite when glucose is found both in the urine and at a high level in the blood.
