Prong collar

A collar of metal links with blunt prongs that pinch the neck when pulled, used for leash corrections and widely debated.

Also called: pinch collar, prong, pinch training collar, correction collar

A prong collar is a chain of open metal links, each with blunt-ended prongs that press on the skin around the neck when the leash tightens. It works by causing discomfort that the dog wants to avoid, so it is an aversive tool.

Supporters say it gives control of strong dogs. Opponents, including many veterinary behavior and welfare groups, say it can cause pain, injury and fear, and can lead dogs to link discomfort with people, dogs or places they were looking at when corrected. It is restricted or banned in some countries.

It does not teach a dog what to do instead, so pulling returns when it is removed. Reward-based leash training, a well-fitted front-clip harness or a head halter are common alternatives. Anyone considering any tool should seek advice from a qualified trainer.
