So, we adopted Rosie Tuesday and she is so adorable and sweet but she is also very rambunctious and she doesn't seem to know any commands. She is still learning "no" and I'm working on "sit" but she cannot stay focused. Does anyone know a really good dog trainer? Preferably one that doesn't use choker chains or prong collars. Someone recommened Petsmart, but I'm not sure that's a good idea. I don't want group training. Help!?
