Thanks Ryan! We met again today with the big dog, Buddy. His owner leashed him to a post and then took Max's leash to do some walking exercises. The expression on Max's face was priceless -- he was smiling, but looking back at me as if to say, "Is this okay, mom?"
We hung out with Buddy for a long time today, just sitting and sniffing and walking a little. Max sat and offered his hand to Buddy's owner -- too cute!
Buddy's owner recommended a local trainer who has a lot of experience in dog obedience competition. I'm looking into signing up Max for classes with the trainer.
Buddy is going to be busy for a couple of days, but I hope to get pictures at our next meeting.
