Has anyone noticed this with their dogs? A couple months ago Molly developed urinary incontinence, this was about the same time we taught her to swim. We found a safe place for her to swim and she loves it now. She is 6 yrs old. After the second outing, she had incontinence not only in her sleep but urine pouring out all the time several days after the swim. Asked the vet if the incontinence was any relation to the swimming and he felt not. We put her on Proin. We tried a dose of 50/day for two weeks, that was not completely effective then increases to 75/day. Molly is 87lbs.This seemed to work. After about 2 weeks on the increased dose, one morning we noticed Molly was panting more, seemed a little excited. We thought the excitement was due to beach outing with other GSDs, but then she threw up. I thought it was related to the Proin, reduced the dose to 50/day again. She was better. No leaks. Thought I'd try to reduce dose again by 1/4. Again no leaks, but we also had no major exercise. Started to add a small dose of a natural product, Bladder Strength. No leaks. We are having our fall heat wave, so we took Molly swimming to cool off. Right away major urine leaking, but only on the day of swimming. Because Molly has had 2 TPLO surgeries, we don't do heavy running or jumping exercise that would stress her joints so we don't know if its only swimming related or exercise in general. Any thoughts? Can dogs eventually get off the Proin?
