Just wanted to give you an update. Marty has been doing a GREAT job!!!!!!!!!!!!! Saturday evening he was tested on our walk several times because we ran into two stray dogs. We managed to avoid them but his walk overall has been great. My boyfriend couldn't believe his eyes when he saw him walking against my knee. Yesterday, was great too. We walked to my sister's to show off. Her boyfriend couldn't believe how well he was doing on a leash. I still have a little trouble with other dogs but it seems to be better than before. I think his controlled state of mind adds to the lack of aggression. Thanks for everything.
