Thanks for the responses.
To help clear up a few things. At Lowes, like I posted, she is kept away from people. We don't enter store, outside, 30' away from people. If anyone wants to pet her, I don't let them, tell story and they will usually talk for a few minutes, 5' to 10', away to help her.
As far as fear aggression, it is not where she tries to attack everyone. With fear aggression, her first instinct is to run. She will try to get away from her fright. If a person, that triggers it,she tries to back up. She will then cower. She will only try to bite if someone reaches for her. We figure that is from previous abuse of being hit.
As far as trainers, we have talked to others and this is not an exact science. Most trainers have different ways and views. No vets in area certified in behavior that we have found to help.
I guess I made her sound like Cujo in my first post, and she isn't. Yes, she is scared but lets you know when, cower, tail tucked, fur up on back. She doesn't attack people at sight, only when backed into what she perceives as a corner and someone reaching toward her which is a threat. If a person stays 5' away, she doesn't have a problem.
If anyone has tried the basket muzzle I would like to hear your results.
