I just wanted you to know, that you getting him (Keeper) in the collar (remote training collar), and showing me how to work with him and the collar, has allowed Keeper to do something healthy, and fun for him, not to mention how happy I am to have him back at the dog park.
He is starting to relax and get back to the way he was when he was younger (Keeper was attacked by another dog at a dog park when he was younger). With only a rare nick at low levels, he is doing great. Today, he was very interactive with all kinds of dogs, he even played a bit.
I know my working with him has a part in it, but you have yet again, improved the lives of a pet and his owner. Thank you again. I look forward to a possible advanced class for Striker, and or more private lessons soon.
Your student, and fan.
