Do you have the breeder's number, would you be able to phone them? If they were an honest respectable breeder they would be willing to help.
Agree that a behaviourist is a good course of action. My dog trainer took on a cocker who had attacked the youngest child in the family, and he felt that the dog was aggressive because he saw himself as higher in the pack ranking then the kids.. he was allowed on the sofa, sleep in the bedroom etc and all the attacks happened when he was in a higher position and/or food was involved.....
Anyway I digress, I wanted to say he turned the dog round instilled more discipline and training. He now is used as a therapy dog with the blind!! So don't automatically feel that she's beyond help, hopefully with a little work it'll sort it self out.
