Boone is a 2 yr old AST Mix who we adopted 2 weeks ago. He has been an amazing dog at home. He never barks at other dogs or people that are out in the complex (we live in a townhouse). This past weekend, I took him home to meet my parents. He was great with my mother, just being a big sook. But my father on the other hand, it brought out a side of Boone we haven’t seen before. He was barking, growling and lunging for my father. It was also embarrassing as I’ve been bragging about how awesome he is and how great his temperament is. The 2 options I came up with were; 1. My dad was scared and Boone could sense it. 2. Since Boone was surrendered, his previous owner may have abused him and just by chance, my dad resembles him.
If someone could please assist so I can have peace between the 2.
