My older dog has developed incontinence in the last few months. He does the same thing-- little dribbles in his sleep mostly, but occasionally big puddles.
We put him on a round of antibiotics for good measure, and then I started giving him an herbal bladder supplement. It's improved things tremendously. No more puddles at least. His issue may also be related to his arthritis-- when he was off Rimadyl for several days, before starting the supplement, is when we noticed the problem (could be pinched nerve due to spinal inflammation). It improved with the resumption of Rimadyl and the addition of the supplement. Who knows which one is doing the job.
I wanted to avoid Proin considering his old age and the cost-- it's basically Dexatrim remarketed for vet use, and I don't trust his old heart to stand up to that. As my vet pointed out, it's wonderful that he's lived so long, but it's so hard to watch him get this old; he has CCD as well as the arthritis. I just wish I could find a less risky alternative to generic Rimadyl, too!
For spay incontinence, I've heard good things about natural hormonal replacement-- things like corn silk and soy can supply the extra estrogen that spayed dogs lack and that helps in bladder muscle control.
Hopefully the Proin will do the trick-- I've known of folks who've had great success with it; I just wanted to offer a few alternatives as back ups!!
