Hamilton Go Boldly Black & Gray Martingale Dog Collar



A martingale collar is a must-have for any outdoor adventure. When connected to a leash, it automatically adjusts to the width of a dog’s neck and will prevent them from accidentally slipping out of their collar.

The gentle correction helps prevent pulling tendencies which can be painful for both pets and their parents.

Martingale collars are adjustable, but do not have a buckle. They are simply slipped on & off over the head. 

Not intended for wearing without a leash
