Martingale collars are a great benefit to pet owners that want a secure collar without it being tight all the time. If your dog tried to get the collar off, it will tighten (Not Choke) and they wont be able to slip it off their head. You can adjust how tight the collar can get when your dog tries to escape.
Cetacea Chain Martingale Dog Collars have a quick release buckle. That way the collar won't need adjusted each time it is taken on or off.
