How to Use a Prong Collar for Leash Training | If You Must

If you’re learning how to use a prong collar for leash training, the first thing to understand is that the experts would rather you didn’t. The American Veterinary Society of Animal Behavior (AVSAB) says reward-based methods should be used instead of aversive tools, and it names prong collars specifically. That advice matters even if you’ve already bought one. This guide covers the expert warnings, the fitting steps, and the mistakes that make a controversial tool dangerous.

Using a Prong Collar for Leash Training: The Expert Warning First

Veterinary behavior experts are clear: prong collars should not be a primary training tool. AVSAB’s position statement on punishment calls for reward-based training only and lists prong collars among the aversive methods it says should not be used.

A prong collar is a metal collar with blunt prongs that tighten when the leash pulls. The intended effect is discomfort that interrupts pulling, but the tool does nothing to teach a dog what to do instead. Animal-welfare groups warn that prongs can cause pain, soft-tissue injury, and damage to the trachea and esophagus, and they can create negative associations with the handler or the environment. Singapore’s National Parks Board similarly discourages shock and prong collars, noting that misused aversive tools carry higher welfare risks.

Repeated yanking or corrections can also worsen reactivity and aggression, which is why behavior specialists recommend pairing any aversive tool with rewards for the behavior you actually want.

How to Fit and Use a Prong Collar Safely on a Walk

If you choose to use one despite the warnings, the safest setup is a snug fit high on the neck, just behind the ears. A collar that sits too loose can create pressure points at the front of the neck and potentially cut off air supply.

Follow this setup for the least risky session:

• Fit it high and snug — just behind the ears, tight enough that it won’t slide down.
• Start in a quiet, familiar place with no distractions, so the dog can learn the signal.
• Use brief, gentle leash pressure and release — never sustained tension or hard jerks.
• Attach a backup safety clip or carabiner to the dog’s regular collar in case the prong collar fails.
• Remove the collar when the dog is unattended; it should not be worn around the house.
• Never use a retractable leash with a prong collar, since it keeps constant pressure on the neck.
• Keep sessions to an hour or less, and stop at the first sign of fear or stress.

Reward that moment. If your dog is younger than five or six months, or is small and light, a prong collar is not a good fit — the tool is intended for larger, untrained dogs.

What Makes Prong Collar Use Dangerous?

Most prong-collar injuries trace back to misuse, not the hardware itself. The most common mistakes are using the collar for punishment or discipline instead of communication, leaving it on when the dog is unattended, and using sustained tension or hard jerks rather than brief release-based cues.

Fitting it too loose or too low on the neck, pairing it with a retractable leash, and assuming the collar teaches good behavior rather than just suppressing unwanted behavior round out the list. A prong collar suppresses a pull in the moment; it never teaches a dog to walk nicely. That is why experts treat it as a last resort, not a first choice.
