Last night at class Mac had a real test.  We were
doing Open out-of-sight downs, and the fox terrier
next to him broke and evidently went right over to him
and jumped on his back.  Mackie has been dying to play
with this dog since class started, but he was a rock.
Everyone is very impressed with him (even if he does
still anticipate the recalls and retrieves). 

Thank you for the great temperament!
