Honestly, I'd be more impressed if there wasn't so much collar popping going on. I love the look of your collars, and might buy one, but I'm not wild about the message that video sends. Even though you are a supporting vendor, I hope it's okay to voice an opinion on the training method used in the video you posted.
I agree with you both.I think I agree with Pawzk9... Really unnecessary. Poor Cooper's front feet definitely leave the ground at least once... I would be interested in a martingale though but I have my eyes set on one from a different company ^^;
