Canine insulinoma refers to a condition where a tumor develops in the dog's pancreas. As a result of this tumor, the pancreas starts producing excessive amounts of insulin. The presence of the insulin reduces the blood sugar levels in the dog. Insulinoma can cause hypoglycemia in dogs, and early identification is essential for speedy treatment.

Lethargy
-
Due to its decreased blood sugar levels, a dog that is affected canine insulinoma tends to act tired and weak. He may be uninterested in play or exercise and even if he is interested, he may tire quickly.
Weight Gain
-
Because the amount of insulin in her body affects the way her body reacts to food and nutrition, and the lethargy that accompanies canine insulinoma, the dog will put on more weight. This occurs even if there has not been a change in the dog's diet or an increase in her appetite.
Excessive Appetite
-
Some dogs will evidence excessive appetite when they are affected by canine insulinoma. They may constantly beg for food or search for it after they have eaten a full meal.
Weakness/Fainting
-
Due to the changes in their blood sugar, the dog may suddenly appear weak or unsteady on his legs. This lack of coordination may come and go, and in some cases, the dog may even faint. According to Davies Veterinary Specialists, this fainting often happens after the dog has not eaten for a while.
Muscle Tremors
-
A dog affected by the large amounts of unnecessary insulin in its body may seem shaky and she may be prey to muscle tremors. This can add to the dog's lack of coordination.
