Thanks! Yes he is very very very mischevious

!! He gets into EVERYTHING! He keeps us very busy (in a good way)

. He's very smart though so he's starting to get what "no" means. We've only had him for a week and a half so he's still adjusting to his new environment. You wouldn't know it though, he walks around like he owns the place! He's so cute it's hard to say no to him!
Are yorkie pups ears not usually up like that??
Thanks for all your responses, I have a lot to learn and look forward to your help.
