Somebody can say to you that Toy Fox Terriers are too active and you won`t be able to train them. It isn`t so! It`s necessary just to know what your dog likes.
Start by sitting with your dog, saying 'shake hands'. At the same time, reach down and take hold of their paw. Do this a couple of times and then give them a treat for doing it. Then, try the command to shake hands again and see if they raise their paw.
