My lil yorkie is 4 months, we got him at 12 weeks, we also have a pure bred beagle that very soon will be 3. Bailey follows him everywhere and has to do every thing he does. It gets frustrating for my beagle , especially when Bailey gets on his blankie, we had to move him to his own for a while, but now he is good at reading signals and knows when to back off. I think in time it is working itself out, he is learning limits and developing his own tricks.
PS- This mimic thing has made it easier to train Bailey tho, lol "out" , "cookie" and "sit" took him all of two days to learn by copying the beagle.
