Review on 🐶 PetSafe Martingale Collar - Adjustable Design that Tightens on Dog's Pulling, Prevents Slipping - Ideal for Strong Pullers, Enhanced Control - Choke Collar Alternative - Available in Various Colors and Sizes by Stephanie Williams

A good friend highly recommended this collar to my husky dog who is a hunter and therefore a puller and so can only be let loose in her enclosure. So the price was right and I tried it. Having only used it once, following PetSafe's instructions carefully and watching a few videos online, I found that after just a few minutes the collar was loose enough for my dog to easily slip out. I quickly got her into an area where I could pull the collar right off her head (yes, it was solved that way) and let her tinker. I was also concerned about a loose loop that, if the collar was working properly, could snag on vegetation it digs into when I let go of it in my territory. Apparently this collar works very well for my friend and many other reviewers but not for my dog. At least it didn't cost much.
