So We got a new puppy recently. She's a large breed mix, half mastiff is all I know. She seems to pee when she is excited or scared. If I raise my voice to her, she pees on the floor. If I go to let her out of the kennel she pees. When some one goes to play with her she pees. For the most part she's figured out she needs to go out side, but this seems uncontrollable. I have tried not letting her get excited, but I have to let her out of her kennel eventually. I don't raise my voice to her, and that does seem to help on that end. Any advise?
