i have two chis - one is golden and behaves like a prince, the other is a brat and behaves as such. she is 2 pounds of fierceness and 'attacks' my bf whenever he visits. she goes for his ankles and grabs on to his pants legs when he walks around the apartment. she never bothers him when he is sitting down or laying down, just when he stands or walks. she will get up from her bed, or wherever she is, to come and attack him at the ankles. i have tried training at a local center, he has tried to bond with her by brushing her, walking her, feeding her treats, petting her, etc. and he, not being a dog person, is giving up and starting to dislike my chi, who is otherwisea great dog, very quiet and obedient. she does this with all men, not just the bf,a nd i noticed just last night, that she does it with women too. as joggers or walkers pass by she will head straight to the ankles as if to bite them or grab the pant legs. i scold her and say no, but she isn't changing the behavior. i work on this a lot with her and the bf but we're not progressing. any tips or thoughts??? i have had her for one year and she is approx. 2.5 years old, about 1.5 yearso old when i got her. a long haired chi if that should matter. thank you.
