Hi, My sons Golden retriever is 2 years old and I have always noticed that she drinks alot, I mean she will drink 1/2 gallon of spring water in one time to her bowl. She has to pee every 2 hours and has a tremendous appetite, but never gets fat. Then I was thinking could she have diabetes? Does anyone know how you go about6 testing your dog for this, and is it normal for a dog to drink so much. I'd say every time she goes to her bowl to drink she just about empties it. Thanks, Jewels
