Dog is on Insulin and Drinking a Lot – Top 3 Reasons Why

Here are a few common reasons that may explain a diabetic dog that is on insulin and drinking a lot.

1. Blood sugar levels are too high

If a diabetic dog is always thirsty, it might mean the dog is having trouble with unregulated blood sugar levels. It might potentially be a sign of a life-threatening condition called diabetic Ketoacidosis. An adjustment to the dog’s insulin dosage might be needed to bring the blood sugar level in line with a healthy range. Don’t adjust the insulin dosage on your own. Consult with the vet to see if any adjustments are needed.

2. Sign of insulin resistance

Excessive thirst and urination could also be a sign that the insulin is not having the desired effect in the dog’s body. Insulin resistance in dogs can be caused by a number of factors including bacterial infections and hypothyroidism. In addition to the dog drinking a lot, you may notice other symptoms like frequent vomiting and lethargy.

3. Causes unrelated to diabetes

The cause that’s driving your dog to drink a lot might be unrelated to diabetes and the effects of insulin. There are many different health disorders that can cause excessive thirst in dogs. It may be a result of conditions like Cushing’s disease, kidney disease, or a bacterial infection. Whatever the reason, it’s important to take your diabetic dog to the vet as soon as possible as some of these disorders may require prompt treatment in order for the dog to recover.
