Title: Better hope your dog isn't too smart
Review: I purchased 7 of these collars. Have put them on 4 so far and 2 are missing already so I put one on another dog and watched. They pull on the tightener part around the neck until it's loose and step right out of them. I thought they would be perfect for leading, but now I have to go out in my 2 acre dog pen and search for 2 of them. Just hope your dog likes it because it was really simple for them to loosen it up and take it off. And just a note, it was 2 different breeds that did it.UPDATE: I have none of these left. Please don't waste your money on these. At least one of seven dogs should of been able to wear this but NO! Every one of them they escaped out of and tore up.
