Two types. One on the right has a swivel so the chain doesn't get twisted at the point where the leash is snapped to the collar. To put this collar on one's dog, one must take one of the prong links and disconnect it from another link that is just like it. Like a string of paper clips. You unfasten one and take the opened collar and place it fasten it around the dog's neck so it is high on the neck. It should fit so the links are not pressing against the dog's neck with any pressure if the dog is not doing anything. For adjustments, You may need to remove or add links in order to get the perfect fit. Rethread the opened link back into it's mate.

A short list of people/dog teams that have benefited from the use of prong collars.

• Small people with large dogs.
• Any person with a dog that seems calm but suddenly bursts into action in some circumstances.
• People with dogs that are pullers. (dogs choke/gag on a slip collar or ignore a buckle collar)
• Disabled people with limited strength or range-of-motion to properly 'snap' correct a dog wearing a slip collar. A light touch is all that is needed.
• Persons 'fine-tuning' a dog's responses to commands.
• Bouncy puppies that are difficult to control in any other collars.
• Walking more than one of these dogs at the same time -- you don't want ride your belly like a skate board while 200 or 300 some pounds of Anatolian in a team or troika take off with you.
• Walking a large protective dog at night in an area where the normally calm dog is walking high on his toes, ready to react before you are. He is on 'predator alert'.

You should be able to control and work with your dog without constantly 'reminding' him what to do... (nag nag nag nag, jerk jerk jerk pull) Nagging a dog on a slip (choke) chain looks bad.

Nagging is not the same as training because the dog is IGNORING your corrections! You are effectively training the dog to ignore you. (this goes hand-in-hand with nagging 'sit-sit-sit-sit-SIT!') We all remember what nagging does to us. It makes me shut down (block it out) or fight back. Our dogs are quite similar in their behaviour.

A prong collar puts power-steering into the handling of a dog, and if the handler continues to maintain an alpha relationship with the dog in training, good behaviours learned while on the prong can be transferred successfully to a milder collar. That is its only used when required.
