Hello! I just got my first chihuahua on Saturday. She is 15 weeks old and weighs 2 lbs. 7 oz., so I imagine she'll be pretty small.. Her name is Josie and she has a very spunky attitude and loves everyone. I did have a question for some of you experienced chi owners though.. Yesterday, my brother (who was trying to have some fun) scared her by pouncing on her from behind. She was freaked out, but appeared to warm up to him again afterwards. However, last night when we were sitting on the couch, he tried to pet her and she growled and snapped at him. Is there anything he could do to repair the relationship? He's only 12 and he feels really hurt when dogs don't like him. Thanks so much!
