I would also agree that it's very odd for a behaviorist to tell you straight off the bat what your dog is and isn't. I had an experience with one such behaviorist who told me through e-mail (without ever seeing my dog) that Ivy was, without a doubt, dog-aggressive. Yeah, okay, lady. That's why we can go to the dog park weekly and have never had a problem. My point is, not all behaviorists are created equal, so there just may be hope for Daisy's life itself.

Contact a reputable, experienced pittie rescue and see if they have the resources and REAL behaviorists who can deal with Daisy's issues.
