She's very pretty, I hope it works out for you. As mentioned, obedience classes would go a long way to solving some of her behaviors. You would have someone who is very dog-savvy to help you with some these issues. 10-months old is still pretty young, and it's a shame no one worked with her before this. of course, if they had, she might not have been "dropped off" in the first place! Some people seem to think dogs train themselves.
Good luck, looking forward to seein gmore pics of all of yours!
