Love this conversation ------ as a breeder I concur with everything that has been said so far (even though my chosen breed is not Doxies). Each dog needs to find it's place in the world and they do this by trial and error (similar to people?) and need a bit of help getting it right when they live in a household. Of prime importance is instilling the idea that YOU are the pack leader and are not to be challenged or questioned. Allow them (in a multiple-dog household) to establish their own pecking order and things "should" run smoothly (kinda) as long as they understand who is the ultimate BOSS!
