One of our girls has spay incontinence. She was spayed around 6 months, (before we knew better), and the problem started when she was around one. She would normally just leak at night, but it wasn't just a puddle. We're talking the sixth great lake, lake Thea! The poor thing acted so ashamed every time. And the bath she needed every time didn't help her feel better!
We have tried just about everything under the sun for it and after three years, (she's four and a half now), we finally have a system that works for her.
First of all she is on Proin. She has been on it since pretty much the beginning and we have had no problems with it. She gets one 50mg tablet twice a day. We had to really play around with both the dosage and the timing of giving it. It really does make a difference if she is getting it at the same time everyday. We recently added a natural supplement as well called Leak No More. The Proin stopped working as well as we wanted and after some research I found Leak No More. It sounds kind of strange, but it has made a huge difference! She now gets it every other night in addition to the Proin and we hardly have an incident.
Some people have used just the Leak No More and that was enough. I think it would definitely be worth a try. But follow the directions, because if you give too much it can make the problem worse. We have also tried powered corn silk. It didn't work for Thea, but our vet has some clients it has worked for. And we tried soy milk for awhile. That did seem to make a bit of a difference, but the amount she required and looking at the cost/benefit it ended up not being worth it for us.
We also cut off her water after a certain time in the evening and make sure she goes out to pee right before bed. Now if she is having multiple episodes in row we know it is probably an uti. She does get them on occasion and it would be something to keep an eye on as having an incontinence problem will make them more prone to getting one.
That's it in a nutshell, but if you have any questions or want to talk more about it feel free to PM me!
