Can dogs get diabetes?-and what are the symptoms if there are any?

Yes dogs do get diabetes. If they are diagnosed then they will be put on a course of thyroxine which should stabilise the thyroid gland and therefore the insulin that is produced should come up to the required levels. 

The cause isn’t known but medical experts feel it could be heredity, obesity and the taking of certain medications increase the chances of a dog developing diabetes. Diabetes mellitus can affect any age breed or sex of dog. though it is generally seen in dogs over the age of four. 

Excessive drinking and urination are the most common symptoms, they are in no way the only ones. weight loss dogs can also develop signs of poor skin and hair coat, liver disease, vomiting, weakness in the rear legs (diabetic neuropathy), secondary bacterial infections and dehydration. They can also develop a life threatening condition known as ketoacidosis. 

Dogs with diabetes suffer because of a under-active thyroid gland strangely enough in cats it is normally overactive.
