What is a Martingale?
A martingale collar is made with two loops. The large loop is placed around the dogs neck and adjusted to fit loosely. The leash is then clipped to the D ring on the smaller loop. When the dog tries to pull their head out of the collar, the tension on the leash pulls the small loop taunt, which makes the large loop smaller and tighter on the neck-- preventing escape.
How to Adjust Properly:
Move the collar up to the narrowest part of the neck & pull upwards on the control loop (this is the part that the D-ring is attached to). The (2) metal slides should come together but NOT touch. There should be at least a two finger distance between the (2) slides (approx. 1 inch).
The proper adjustment will ensure the collar will continue to tighten when you need it most, preventing the collar from slipping off.
