We got Anna from a shelter in May. She was a retired breeding dog who had spent the majority of her 6 years in a cage as a breeding machine. She's not very well socialized. She is very loyal and protective of me and her bond with my husband is growing, but she is just down right nasty to my 19 year old son. He moved out in August for college. He comes home on the weekends for his job. She barks non stop at him and nips at his ankles anytime he walks through the house. He deals with it ok. But I can tell that it bothers him. It would bother me too. I am not sure what to do. She does this with all of our guests. However, most guests are not here more than a few hours so we can put her in the bedroom until they leave. The vet has given her anxiety meds but when she's wound up they do not do anything for her. I have tried turning my back on her and scolding her sharply. I would appreciate any advice. Is it too late to change this behavior?
