Do you think that maybe Memphis is just trying to tell Corbin that he is Alpha?
Be sure to stick w/a firm NO when he does this behavior. Regarding the can (I too was using one w/coins in it) I was speaking to a dog trainer who says the can and the water bottle are the two worst things you can do to try and stop a particular behavior especially in toy breeds. He says it usually will just make them more anxious then ever!
I am sure some other Yters will have a great advice!
Good luck |
