Marilyn, When she started having symptoms she would drink excessively and then have to uninate a lot. She started to loose weight even though she seemed to eat normally. Then she got so she couldn't make it through the night without asking to go out. Once she got regulated she put the weight back on as was doing great, but then started to drink a lot again, and couldn't make it through the night without having to go outside. She'll be 10 years old this spring, and my vet told me that most likely she will develop cataracts as that seems to be what happens to dogs with diabetes as they age.
