check out your library videos of The Dog Whisperer. I only have one Yorkie, and he has always been calm little guy @ 5 1/4 lbs.
I do remember seeing several of the t.v. episodes of "The Dog Whisperer" starring trainer Caesar Milan on the National Geographic Channel (not sure of his last name's correct spelling). But he did work with many family's pet dogs who would go after another family dog at home, and even dogs who tried to attack strange people or their dogs during outdoor walks. It would take too long to describe the basic methods he used, but if you could watch a couple of his shows where he dealt with this "attacking" issue within one household's dogs, you may get some really good techniques to try. The dogs were of all breeds and sizes! Our library has a series of these tapes and the shows still run on t.v....so watch some until you see him work with your dog's same issue. I know he did deal with dog attack issues quite often.
Good Luck! (She has to basically realize she is Not allowed to attack him, period) |
