My dog Tosh may have diabetes. He's been peeing in the house a few times and has lost weight. Plus he's blind in both eyes now due to cataracts. He's about 10 years old. I don't understand how he developed this. He's always been healthy, I walk him about 4-5 times a week, always feed him, and he's rarely had a bladder problem (Only when he gets really excited). I fear he may be reaching the end of his life, and it's something I really do not want to go through with. I'm really attached to him, like he's a brother of mine. Have you gone through something like this? If you have a diabetic dog how do you take care of him?
