Just in case anyone was interested in an update -

WOW there is so much improvement! I took him out on a four hour hike to a new park. He of course barked at first but the first time you say no to him he stops! He still gets sprayed from time-to-time but I have been bringing this on every walk (including neighborhood walks & hikes) and he's just behaving so well now. He was incredible. He's a changed dog. Toward the middle of the hike, he'd just look at them and whine, but he didn't bark! I just had to say "NO" and he stopped. I am so proud. I will keep bringing it with me of course, but he's just so good now.

He still pulled some Mikey antics -
-tried to bring me a dead mouse/bat...thank you but no thank you Mikey
-accidently peed on my friend. He was peeing on a post and missed, she was sitting right in front of him.
-Almost fell into the water a few times.

Also, some geese came over to us on one of our breaks (probably expecting food) and Mikey is so respectful of them. Of course the wuss may be a little scared but he doesn't bark at all..so I really don't need to worry about *bigger* wildlife.
