Thank you for your replies...It's what I needed to hear. I don't want to do anything in haste and be judged that we did not give this rescue a chance. Actually, I'm more concerned about Maggie at this point.

Maggie is 10 (almost 11). Deep down I know I should send him back...I was hoping that this was going to be is "Forever Home", but we do have to think of Maggie...she has earned her right in our household to live out the rest of her days (hopefully a couple more years) in peace and quiet. And right now, her whole quality of living has been disrupted.

I have explained the situation to the rescue and foster people..their replies were to focus our attention on the Dane and not to leave the two dogs unsupervised (no kidding). And after a couple of weeks, if we don't see any improvement with Maggie, we can return him to the Dane Rescue. Do you think a couple of weeks is too long to chance?

I think I know what I have to do.

Thank you so much
