Diabetes can be managed successfully with a daily routine of insulin treatment, diet and exercise

What do I need? Syringe

1. Insulin

Veterinary-approved insulin has a concentration of 40 IU/ml. Use the correct insulin syringe (U-40) or specifically calibrated insulin injection pen (VetPen) to administer.


The first insulin approved for both cats and dogs and the only veterinary insulin to offer you a choice of how it is given1.

2. U-40 Insulin syringes

U-40 syringes used with Caninsulin® 2.5 ml or 10 ml multidose vials. Traditional way of administering insulin injections. Less accurate than injection pens at low doses. Risk of dosing error if incorrect type of syringe is used.

Spaying Female Dogs

Insulin resistance is caused by the ovarian hormone progesterone. Surgical removal of the ovaries with or without the uterus (spaying – ovariohysterectomy or ovariectomy) will make your female dog’s diabetes easier to manage. There is also a small chance that your dog’s diabetes may not be permanent. If diabetes mellitus has been diagnosed in your intact female dog, spaying should be carried as soon as possible if your dog is feeling well. If your dog is unwell (not eating or drinking and has very high blood glucose) then your dog may require rehydration (sometimes via an intravenous infusion) and insulin treatment before the surgery can be carried out.
Following surgery, the response to insulin will often improve and the insulin demand will decrease accordingly. These dogs need to be monitored carefully as some may cease to need insulin injections.

Starting Insulin Therapy

Your veterinarian will calculate a suitable insulin dose, based on your dog’s body weight.

Your veterinary team is there to help you. They will teach you everything you need to know about giving insulin injections. They will recommend appropriate diet and exercise and advise you on how to best monitor your dog’s progress. Shortly after starting insulin treatment, your dog’s signs should start to improve – your dog will be less thirsty, urinate less often and feel better. Pay close attention and record these and other changes, including your dog’s appetite and attitude. Your veterinarian may need to adjust your dog’s insulin dose, based on how well your dog is doing and the results of follow-up tests (such as blood glucose measurements). A consistent daily routine, monitoring plan and communication with your veterinary team are key to managing your dog’s diabetes.

Once or twice daily treatment?

While some diabetic dogs can be managed on once daily insulin injections, many dogs need twice daily insulin injections to manage their diabetes. animated dog named Spike with quote about diabetes treatment

“I was worried about getting injections at home, but now that I feel like my fun-loving self again it’s all worth it.”
