Quick answer
The COA Halti Headcollar Size 3 fits dogs with a nose circumference of 25–40 cm and a neck girth of 30–55 cm. To fit it correctly, adjust the nose loop so it sits 1–2 cm below the eyes without slipping, and the neck strap should be snug but allow two fingers underneath.
Why fit matters
A correctly fitted headcollar gives you gentle control without causing discomfort. If it is too loose, the dog can paw it off; too tight and it may rub or discourage use. The Size 3 is designed for medium to large breeds such as Labradors, Golden Retrievers, and Border Collies.
Common trade-off
A headcollar works by steering the dog's head, not by force. Some dogs initially resist the sensation. Pair fitting with positive reinforcement—treats and calm praise—so the dog accepts the collar before you start walking.
Step-by-step fitting guide
- 1. Adjust the nose loop: Hold the headcollar so the metal ring sits under the chin. Slide the nose loop over the dog's muzzle. The loop should rest 1–2 cm below the eyes—high enough to avoid slipping off but low enough not to press on the eyes. Common mistake: placing the loop too far forward, which lets the dog pull free.
- 2. Fasten the neck strap: Bring the strap behind the dog's ears and clip it. The strap should be snug—you should be able to slide two fingers between the strap and the dog's neck. If you can fit more, tighten it; if less, loosen it. Common mistake: over-tightening, which can cause rubbing or breathing discomfort.
- 3. Attach the lead to the control ring: Clip your lead to the metal ring under the chin (the main control ring). Do not attach the lead to the D-ring on top—that ring is for the safety strap only. The safety strap clips to the dog's regular collar as a backup. Common mistake: clipping the lead to the top D-ring, which can pull the headcollar sideways and reduce control.
- 4. Check for movement and comfort: Let the dog move around indoors for a few minutes. The nose loop should not slide forward past the dog's nostrils, and the neck strap should not twist. If the dog scratches at the headcollar, it may be too tight or the nose loop is too low. Common mistake: skipping the indoor trial and heading straight outside, where the dog may panic and try to remove the headcollar.
