My mom's 15 year old poodle/beagle mix has had problems oer the last few months being able to control her bladder. She is now on medication that has helped. I believe her problem is age, but I have heard of other females having this problem once they are spayed. If she is able to control it with medication, that seems to me, like a better option then surgery (unless of course there are long term affects of the meds)
