    Just like humans, your canine companion relies on glucose, or blood sugar, for fuel. Glucose powers every single cell, from organ cells to brain cells. Ideally your pup should have a blood sugar level of 75 to 120 milligrams per deciliter, shown as mg/dL, PetMD reports. But when something isn’t working right, his glucose could be out of this range, which can be extremely dangerous to his health.

    High Blood Sugar

    High blood sugar, called hyperglycemia, occurs when your dog’s glucose goes over 120 mg/dL. Pancreatitis can cause high blood sugar, since the pancreas is responsible for making insulin, the hormone that allows cells to use glucose. This can lead to canine diabetes. High blood sugar can also stem from poor diet, a hormonal imbalance or an infection.

    Low Blood Sugar

    Hypoglycemia sets in once your furry friend’s sugar dips below 75 milligrams per deciliter. The most common cause of hypoglycemia is an overdose of insulin if you’re already treating your pooch for diabetes. If your dog is not diabetic, low glucose levels are usually a sign of a serious condition, such as a tumor.
