Our dog is 12 going on 13 and she developed some night time incontinence...vet told us this was common in older females and prescribed estrogen tablets, brand name Incurin...we give her one a day and remember the last thing we do before we go to bed is wake up the dog and let her go out to pee...so far so good.
Here she is helping me out in the garage
Snowman let us know how you make out at the vet...our other dog mas a large male mix, and when he started to become incontinent the vet said it was lymphoma and he only lasted another 2 weeks.
