Hey!!, my name is Fer (like fair) and I'm new in the site and just wanted to say hello

I'm mommy to Rambo a 14 week old Yorkie Biewer.
I do have a couple of questions, Rambo chews everything in site! He even tried to chew on the wall a couple of hours ago! He has tons of toys so I don't know what to do! I did put some vinegar in the edges of my furniture because he tried to chew there too, but I don't want my whole house to smell like vinegar!

And do you know if his ears will stand up again? When I first got him both of his ears were up, after a couple of days one went down and the next week both of them were!
Here are some pictures of the little one
I'm so excited to learn more about this awesome dogs!
