How do I teach my dog to open doors.

[Tuskarr]

First you open the door, but make sure he watches you. After that take his hand and make him open the door. He wouldn't learn so slap him in the nose or cheek and make him do it again. After you do that a bunch of times I am sure he will learn it. But don't slap him too hard.

Lots and lots of treats. Emulate what you want the dog to do, a playful dog that bites at it would be the best.

Dog whisperer could do it, so can you

Thats a tuff one but you got me very curios on this one wish more people will post.

haha that would be so funny! It would be kind of creepy though.

First I think you should try teaching the dog to bite the glove. Like fetch.

Put it near his mouth and get him to bite it, then pull on it. Once the door opens give him praise and a treat.

Yeah this idea may be the best.
Dude, your dogs gonna run away if he knows how to open doors :[
