From my experience there are events that can throw them off their training. It could be her time at the groomer was upsetting for some reason. I don't like the idea of leaving my dog at the groomers for hours at a time. They are usually kept in small cages and they are not let out to potty. It is also a good idea to have a dog checked out by the vet whenever something this dramatic happens.
My Gracie also was easily pad trained. During her first year there were a couple of times she just suddenly started peeing next to the pad instead of on it. It was always when there was a change in things in the home. One time it was when my daughter moved back home. I just had to start watching her very closely like starting training all over again. I would give her a treat every time she got it right. It was only a matter of days that she was back to using the pad regularly again. One time I also went out and bought a liquid house breaking aid to put on the pad. They help to attract the dog to pee on that spot. I know the pads are supposed to already have the scent on them but I figured that you can't always trust these pet product companies so maybe a fresh attractant would help. I also make sure the frame that I keep the pads in was cleaned after every pad change. Some dogs will avoid a dirty potty area. |
