I have dealt with it with our 14 year old Lab, Murphy. Most of the wetting problems were occuring when she was sleeping. She started out taking DES (a prescription medication from our vet) every 3 days and for a while it worked. Later, it stopped being so effective and he added Proin (pheno....something...sorry I don't have the bottle handy), but the combination has helped dramatically.

Talk with your vet. This is not an uncommon problem at all and the medication may help, once they rule out any kind of bladder or kidney problems.

Good luck to you.
