I am adopting a three year male yorkie named Leo. He is a great dog, knows tons of tricks such as sit and stay come and so forth, is completely house broken from what i have seen andbeen told. But my worries are when I bring him to my house the first day if he will relapse out of those things he knows, like the potty training and so forth. Any advice and what i should do? Any advice is welcomed thank you for all of your time and have a nice day.
