Diabetes in Dogs

Monitoring Urine Glucose & Ketones

Tracking Diabetes in Your Dog’s Urine

Monitoring Glucose and Ketones in Your Dog’s Urine

Immediately following diagnosis, your veterinarian may ask you to check your pet’s urine to monitor glucose and ketones. Depending on your pet, this may be done 1–3 times a day:

  • Early in the morning, just prior to the time of the Vetsulin® injection and first meal
  • Late in the afternoon, before the second meal
  • Late in the evening

If monitoring once daily, the measurement should occur at the same time every day.

Collecting Urine

As treatment progresses, less frequent testing will be needed. Regular examinations remain important though, because your dog’s insulin needs can change.

Tools for Collecting

  • Clean containers for collecting urine
  • Urine dipsticks from your veterinarian
  • A place to record results

How to Collect

  • Take your dog out for a walk on a leash. Keep your dog on a leash so that he will be within reach when he urinates
  • Have a clean, dry container (dish, bowl, or small pan) ready to catch urine when your dog urinates
  • When your dog begins to urinate, slowly slide the container under the urine stream
  • If needed, long-handled devices are also commercially available to help facilitate urine collection

VETSULIN® and VETPEN® are for use in animals only. Dogs and cats known to have an allergy to pork or pork products should not be treated with VETSULIN®. VETSULIN® is contraindicated during periods of hypoglycemia. Animals with severe ketoacidosis, anorexia, lethargy, and/or vomiting should be stabilized with short-acting insulin and appropriate supportive therapy before use. As with all insulin products, careful patient monitoring for hypoglycemia and hyperglycemia is essential. Overdosage can result in profound hypoglycemia and death. Progestogen and glucocorticoid use should be avoided. The safety and effectiveness of VETSULIN® in puppies, kittens, breeding, pregnant, and lactating dogs and cats has not been evaluated. Keep out of reach of children. Avoid contact with eyes. In case of contact, immediately flush eyes with copious amounts of water for at least 15 minutes. Accidental injection may cause clinical hypoglycemia. In case of accidental injection, seek medical attention immediately. Exposure to the product may induce a local or systemic allergic reaction in sensitized individuals. For complete safety information, refer to the product label.
