RE: out of control peeing lab
Like jay7108 said, the very first thing to do is get to a vet and have her checked for a UTI, the sooner, the better.
Ifshe shows up negative for a UTI, then you probably have to start all over with housebreaking. For whatever reason, some dogs seem to regress at about that age. There is a very good book (IMHO) on housebreaking called How to Housebreak Your Dog in 7 Days by Shirlee Kalstone that we recommend to our puppy buyers. Good book if you have not had a lot of experience in housebreaking dogs. It sells used on Amazon for $3.98 or so.
