Diabetic dog's blood sugar high after insulin. What are my options?

Updated On September 23rd, 2025

Pet's info: Dog | Lhasa Apso | Male | neutered | 16 years old | 24 lbs

My 15 year old Lhasa was diagnosed three months ago with diabetes. The vet prescribed 12units Novolin N. He has since lost another 5 pounds but, his numbers are still high...450+ four hours after insulin. Vet says bring him back in three months. Can this be the best I can do for my bud? What are my options?

Most regulated diabetics hang around 200 for their glucose and the weight should be stable. he needs a glucose curve with a urine test to check for ketones and have his dose adjusted. He also should be checked for concurrent diseases that can lead to insulin resistance such as hypothyroid, Cushings or an infection. From there, there is another type of insulin that some regulate better on and it may be worth looking into Vetsulin. A diet change to a diabetic friendly one can also help regulate diabetes. It is frustrating but you do have a lot more options worth pursuing
