The prong collar is one of the most controversial training tools in the dog world. Some professional trainers swear by them, others are categorically against them. The truth is probably somewhere in between. A prong collar is a specific tool that, when used correctly and skillfully, can be effective — but when misused, it can cause harm to your dog.

1. What is a prong collar and how does it work?

A prong collar (also called a pinch collar) is a metal collar made up of interlinked chain links with inward-facing blunt prongs. These prongs are not sharp — on a quality prong collar, the tips are rounded and smooth. When the dog pulls, the pressure is distributed evenly around the entire neck.

This distinguishes the prong collar from a regular choke chain, which applies pressure to one point on the throat and can damage the trachea. The principle of the prong collar is to give the dog clear and even feedback.

A prong collar does cause some discomfort to the dog, signalling that it has done something incorrectly. A trainer or owner who claims that a prong collar causes no discomfort whatsoever is not being honest. Acknowledging the discomfort does not automatically make the prong collar cruel — rather, it helps you use the tool more responsibly.

Prong collars are banned in several countries, including Australia, New Zealand, Austria and Switzerland. They are not banned in Estonia, but international regulation indicates that this is a tool requiring special attention and responsibility.

IMPORTANT! A prong collar should only be used during short training sessions and preferably on the recommendation of or under the supervision of a professional trainer. It is not suitable for continuous wear or everyday walks. Incorrect use can cause discomfort or injury to the animal.

Herm Sprenger themselves state clearly: "Prong collars are not recommended unless other training methods have been exhausted."

2. Common myths about prong collars

Myth: "Prong collars are cruel and cause pain." When the correct size is used properly, the purpose of a prong collar is not to hurt the dog, but to create clear and brief pressure or discomfort. Problems most often arise from incorrect use, corrections that are too strong, or continuous wear.

Myth: "Prong collars are only for aggressive dogs." Prong collars are widely used in obedience training, sport dog training and working with reactive dogs. They are not a tool reserved only for "problem" dogs.

Myth: "A cheap prong collar does the same job." This is a dangerous myth. Cheap imitations often have sharper prongs, weak connections and uneven pressure distribution. Herm Sprenger has been manufacturing prong collars for over 140 years and their design is specifically engineered so that the prongs face away from the trachea.

3. Who is the prong collar suitable for?

The prong collar is best suited for strong, energetic and pulling-prone dogs that are difficult to control with conventional tools. It is widely used in sport dog training — IPO, obedience, police and search and rescue work. It is also used when working with reactive dogs, where clear and quick feedback is important.

The prong collar is not suitable for puppies or young dogs whose bones and muscles are not yet fully developed. It is also not suitable for dogs with neck or back problems.

At Petworld, the prong collar is one of the most frequently requested training tools — most often sought by owners whose dog pulls so strongly on the leash that walking together has become difficult or even dangerous, though in many cases the problem can also be solved with other training methods.

Our recommendation: If you are unsure whether a prong collar is the right tool for your dog, consult a professional dog trainer before purchasing.

4. When to consider a prong collar?

A prong collar should not be the first choice. Before trying a prong collar, it is worth going through other options and working with a professional trainer who can help find the right approach for your dog.

  • Front-clip harnesses — the leash attachment point at the chest automatically redirects a pulling dog back towards the owner
  • Easy leaders — provide additional control over the head, especially when working with reactive dogs
  • Martingale collar — provides moderate feedback when pulling, without the intensity of a prong collar
  • Positive reinforcement training — systematic loose leash walking exercises with a professional trainer and reward-based motivation

If you have genuinely tried different methods, worked with a professional trainer and your dog is still not making progress, a prong collar may be the next step — but always under the guidance of a trainer.

5. How to choose the right size and material?

Herm Sprenger prong collars are available in several wire gauges and materials:

  • 2.25 mm — for small breeds
  • 3 mm — for medium breeds, also suitable for more active Malinois-type dogs
  • 4 mm — for large and powerful breeds

When choosing a material: stainless steel is durable and suitable for all weather conditions. CUROGAN is a nickel-free alloy, ideal for dogs with sensitive skin or metal allergies, and does not leave marks on light-coloured coats. Black prong collars are more discreet and well suited for competitions.

The prong collar should sit high on the neck, just behind the ears. A collar that is too large will hang low and will not provide even feedback. Links can be added or removed to achieve the exact right fit.

6. Correct use

A prong collar is not an everyday walking collar — it is a training tool to be used only during training sessions. After training, the prong collar should be removed and replaced with a regular flat collar or harness.

The prong collar is used with short, clear corrections — not continuous tension. If the dog is constantly pulling against the prong collar, either the collar does not fit correctly, is the wrong size, or the dog needs a different approach.

What not to do:

  • Do not use a prong collar on a puppy — it is not suitable for young dogs physically or psychologically
  • Do not leave the prong collar on your dog all day — it is a training tool, not a walking collar
  • Do not use a prong collar as punishment or to express frustration — this damages your dog and your relationship
  • Do not use a prong collar without checking the size — the wrong size means uneven pressure and potential injury
