If you have a Japanese chin, by now you know they love attention. One very annoying way they try to get attention is by grabbing a knick or other object and running off with it to induce someone into a crazy game of chase. Put a leash on your puppy so you can easily catch him. You'll have to watch him so the leash doesn't catch on anything. But you also won't be running after your little thief either. Once you grab your puppy after he stole something, quickly remove whatever he has. Most people recommend squeezing a dogs snout to induce them to drop the object, but Japanese chins don't have much of a snout to squeeze. Most of the time you can get them to give it up by holding them firmly and forcing them too.
