My one Yorkie went through a brief stage and wanted nothing to do with our other Yorkie and would attack her if she came on the same floor as her (formerly the best of buddies). I got a small muzzle and every time she started to get nasty on went the muzzle and we all went about our business, leaving her sitting there amazed we would do such a thing! She was smart enough to learn very quickly that when she gets nasty on goes the muzzle. That was 2 months ago and the problem was corrected after two days of "muzzling" (we would only muzzle for a few minutes at each negative encounter) Now they are back to playing and loving each other. It corrected her getting nasty/overly protective with some people also.
I had tried the spraying with vinegar and water, the positive treat reward, just about everything, then I decided as a last resort effort to get the muzzle (a size "2"?/cloth/Petsmart) - best thing I ever did. I think it worked because once her power was removed and she learned we do in fact have that power over her she figured she better go with the expected flow. She started to get nasty the other day when a new person came over and I held up the muzzle and said do you want the muzzle? and she quickly got nice, so she remembered. Anyway, it's worth a try for you.
