Qualified behaviorists can be found here:
Depending on the situation, this kind of dog can come around …they take a LOT of work, and committment and management. A lot of behaviorist will refuse to work with a dog who has bitten kids who live in the home, because of the liability issues. There are a lot of variables involved. Often the most responsible thing is rehoming of the dog.
That being said, Ivy has bitten (snapped) at Ethan twice over the three years they have lived together. We work on it, we manage it, we know that having Ivy here is a risk, and we know it is our responsiblity to teach Ethan how to behave so as not to get bitten. And we know it is also our responibility if he does get bitten. The alternative for her is euthanasia, because I will not rehome a dog that has bitten in the manner she has (she has bitten adults as well). So we work, and we work, and we super carefully manage her.
