Hi all, I'm taking care of a dog for a friend this week. I'm starting to wonder if he could have diabetes because he is constantly drinking water, which leads to peeing a lot, so much that he can't go more than 2 hours. I'm going to limit his water intake, but I have to wonder if there's a reason. Does anyone know what a normal BG range is for dogs? Do I test him on his ear like I do with Rex? I use a ReliOn Confirm meter. Background on the dog: Brittany Spaniel, about to turn 14 years old, has a brain tumor, which led to one eye being removed, has a cataract in his other eye, is going deaf, and also has severe vertigo.
