My Girl Only Likes Her Little Brother Now
For context, my 4 year old Husky has historically been extremely friendly and playful towards other dogs, even to the point of when they showed slight aggression she would keep trying to play.
However about a year and a half ago, we adopted a boy, a rescue pit/German mix. They love each other very much.
After we had them together for a while, anytime I bring my husky near other dogs she shows signs of aggression. At first it seemed like she was only doing this around her little bro, but this morning I tried to introduce her to a neighbors dog and she got snappy. I had to apologize, the neighbor was cool about it, nobody got hurt, it was just a quick growl and bark combo that didn’t sound happy. However, is this something that has permanently changed in my dog? Will she ever be cool around other dogs again or is it just her and her bro for life now?
