Looks like you've got lots of great advice. The only thing I'd like to add is that you might want to consider teaching Meg hand signals. My Clancy picked them up on his own, luckily for both of us, as he is now 14 and deaf. It has made it possible for me to continue to communicate with him and still allow him to be off-leash on hikes and walks on the beach. Any future dogs I acquire will be taught hand signals on purpose, 'cause they may not be as clever as Clancy the Wonderdog!

PS Wicked cute pup.
