After the first time I tried the Easy Walk on Teddi, I knew I'd never go back to the regular harness! The hardest part was the fitting but once that's over with, it's so easy to put it on/off.
I did, however, end up switching to the Gentle Leader harness because it was more effective against pulling when something distracts him from the walk (e.g. kids playing nearby). That one was a little easier to fit but a little harder to put on. But, either one's a good buy!
