Wonderful collar for dogs w/a lot of hair or big necks. I prefer this collar with the buckle over the ones that slide over the head because some dogs don't like having a collar slid over their ears, and the collar doesn't need to be tightened/loosened to get on/off. The chin slips freely to allow a small correction and return to loose position quickly, unlike most nylon slips that have a slower return time.
I bought this because my shar pei pulled when ever she saw another dog she loves dogs so always wanted to go and see them even when they were across the road.A friend told me to get this because a reg collar doesn't work to control her this works like a charm one or two pulls with a no and she stops so now walking her pass other dogs is so easy.I've even bought one for my friends dog.Only collar I'll use from now on.
