You just posted another thread saying Thanks for nothing," but it may be that others just missed it, like I did the day you posted it. I was shoveling snow as we were in the middle of a two day storm then.

You need to reestablish not dominance but control over your dog. Do you make sure to spend time with just her? Does she still get walks, etc. with you? What is your normal routine, in terms of treats, food, etc.? What breeds are the dogs, and are they both neutered?

We'd really need to know more to be able to help.
