Dear Adam,
Hi, I have a 3 year-old Australian Cattle Dog. She is a wonderfully obedient dog, canine good citizen certified and everything. She is very obedient and good natured to people, however she is very dominant when it comes to other dogs. Recently I have been having problems with her snapping at other dogs if they come up to her while she is on a leash. This is not a problem if I tell her to sit and the other dog stays a normal distance away. She doesn’t like dogs invading her space and standing over her (she is only 35 pounds, so most dogs tower over her). I call it her “Napoleon Complex”. I tried to work on the problem by putting a muzzle on her and setting up situations so I can correct her, but she realizes that she is in no position to show the other dog who is boss while muzzled and refrains. We have recently started therapy dog training classes, which she is doing very well in.
Like I said she is a perfect angel around people. In a therapy situation she is unlikely to encourage other dogs on or off leash who will be allowed to be in a position close enough to upset her, however, if some instance did occur, I would feel uncomfortable...
