alice's mommy and jlaack are right. No more excuses -- no more waiting for one person to call you back. This is not a situation where you should wait on one trainer to call you back. Call Amanda again, check for other assessment resources... and get this dog seen, ANYWHERE the two of you can get to a competent trainer/behaviorist, as soon as possible -- and act immediately (and continuously, re: training) on their recommendations. This has to be a priority in your life. You owe Rosco that and more.
