Choke chains or collars are metal link collars that are designed to inflict pain when a dog misbehaves (i.e. pulling on the leash when walking). There is definitely a lot of debate on whether or not this type of collar is a humane method of training. With the collars are still available in some stores and online, you may find yourself wondering if it would work for your dog. The best way to answer this question is to talk to your vet about your dog first. You may also want to talk to a dog trainer as well. Many experts recommend avoiding these types of collars because they can be dangerous and cause injury even when used the right way. If you insist on using one of these, it is suggested that you receive professional training on the correct way to use the collar.
