Insulin prices for diabetes in dogs can vary greatly. Although the average range is between $40 and $150 per month1, it can sometimes cost as much as $400. The difference comes down to your dog’s specific dosage and where you buy the insulin.
Larger dogs will typically need a higher dosage, resulting in a higher monthly cost. Your vet may be able to help you find a cheaper source of insulin, or you can search online to compare costs. Either way, you should always discuss the topic of medication with your trusted vet.
