How old are the dogs Sherri? Anyways, it sounds like they have some long standing behaviour problems. If you end up keeping them I would hire a reputable dog trainer ASAP. It is probably expensive, but it sounds like you are paying a lot already, and your house is being destroyed as well. I think the rescue center should have been upfront about their behaviour problems, but they obviously weren't. It will probably be a lot of work, good luck!
