I just recently got a German Shepard puppy from a Breeder. She is 4 months old and had been living in an outdoor facility on a ranch. It was all concrete and dirt or hay there so now I am having a lot of trouble potty training her at my home. She keeps going on our tile in our kitchen or bathrooms and doesn’t seem to understand the concept of going on the grass in our yard even though she sees our other dogs do it. Any help or advice please!
