I use both and I like the Easy Walk for daily walks and the Gentle Leader for "situations" like walking through a crowd. Loki needs to be managed since he will bark at other dogs, so the Gentle Leader helps with that. If you are only dealing with a puller and not a barker or a reactive dog, the Easy Walk would be my recommendation. It is simple to use and easy for the dog to adjust to and most important it is as comfortable as any other harness. The GL takes a period of adjustment - some dogs do well with them and others don't like them.
I have the full size range of Easy Walks on my website
Barkaholics — Welcome and I have some size small Gentle Leaders that aren't on there, but PM me if you are interested. Let me know if I can answer any other questions!!!
