I would definately take her to the vet. It might be something wrong with her kidneys. I had two poodles, and both of them had kidney failure. My oldest one started piddling without even realizing it. The poor thing would be standing in the kitchen and the next thing you knew there was a puddle underneath her. I attributed it to simply being so old, but then she started acting strange. She seemed to be disoriented, etc. Take you furbaby to the vet.
