I've used the Easy Walk harness for both my girls for over a year - Gemma can slip any other kind, and so can Shay. Gemma can even slip her collar. The Easy Walk gives me good control when they are suddenly off chasing a squirrel to the end of the lead, and since they are not tight in the front, where the ring is, they are not overly restricted when they walk well. Which they do seldom.:rolleyes:
