Learn how to fit a COA Halti Headcollar Size 1 on a small dog. Follow these step-by-step instructions for a secure, comfortable fit that prevents pulling.

Quick answer

To fit a COA Halti Headcollar Size 1, adjust the nose loop and head strap so the headcollar sits snugly but not tight, with the metal ring under the chin. The fit is correct when you can slide one finger between the webbing and your dog's skin.

Why the right fit matters

A properly fitted headcollar is key to preventing pulling without causing discomfort. If the headcollar is too loose, it can slide off or rub; if too tight, it can restrict breathing or cause chafing. The COA Halti Headcollar Size 1 is designed for small dogs, and getting the fit right ensures both safety and effectiveness.

Check the size before you start

Before fitting, verify that Size 1 is appropriate for your dog's head circumference. This size suits very small breeds, but if your dog is between sizes, you may need to adjust the straps more carefully or consider a different size. The headcollar should not press on the eyes or the nose tip.

Step-by-step fitting guide

  1. Loosen the straps: Before placing the headcollar on your dog, fully loosen both the nose loop and the head strap. This makes it easier to slip on without pulling fur or causing stress. Check that the straps move freely and are not twisted.
  2. Position the nose loop: Slide the nose loop over your dog's snout, positioning it high on the nose, just below the eyes. The loop should sit comfortably, not pressing into the eyes or the tip of the nose. Make sure the nose loop is not too far forward or backward.
  3. Fasten the head strap: Bring the head strap behind your dog's ears and fasten the buckle. Adjust the strap so the headcollar sits securely but not tight. You should be able to fit one finger between the webbing and your dog's head. Ensure the headcollar does not twist or slide sideways.
  4. Check the fit and attach the lead: Once the headcollar is in place, check that the metal ring rests under the chin. Attach your leash to this ring. Give your dog a treat and let them wear it indoors for a few minutes to get used to it. If the headcollar shifts or causes rubbing, re-adjust the straps.
