We have 4 English Bulldogs who are pullers when on a leash. We used a different harness that helped reign them in, but they had to step through the front loops, then connect the collar around their neck. No one cooperated. Then I saw a video for Joyride. Game. Changer. It was worth every penny to buy 4 at the same time. Now it takes less than 2 minutes to get all 4 harnessed up & ready to go. And they no longer pull at their harness, so the pups like them, too. Plus, the chest design means that even if they do pull, I'm not worried about undue pressure on their windpipe. I highly recommend Joyride - easy on, easy off, fantastic design.
