My female border collie/lab mix is almost 11 years old, and about 6 months ago started having "accidents" almost daily. The vet did numerous tests and x-rays to rule everything else out and concluded she was incontinent. He said it was common in older females due to being fixed at a young age. She seems to be doing fine on it...the accidents are rare now, but I'm concerned about side effects with prolonged use. I can't really find much on line so wondered if anyone else has used this on their dog.
