Is your dog still a pup or is your pup an adult? I think you said it was a pup.The reason I ask is because a few years ago I used to have a rat terrier named Star. Well anyways Star was very hyper and she used to do the same thing as yours. There is good news, but it may take a while. She gave up the pee pee habit when she got out of her puppy stage. Atleast yours didn't pee on the couch out of excitement while you were playing with her. So hang in there and Goodluck. There is still hope for you.....................
Also it my not be the same case as mine. Yours my get better at it. So don't worry. Enjoy your furbaby. No matter the case they are worth it. I'm sure you agree.
