If It Barks reflective martingale dog collars with buckle, also known as limited slip collars, are highly recommended by dog trainers over your standard buckle collar or less humane choke chains. Benefits of Martingale Collars: - Dogs with small heads and big necks are not able to back out of the collar like traditional buckle style collars. - Martingales provide better control while walking your dog by applying even pressure around their neck. This reduces injury and choking. - The collar is constructed with two loops of webbing. One wraps around your dog's neck and the other is used to control the amount of closure of the collar when your dog begins to pull. How you adjust the collar determines the allowable closure. Features: - Genuine 3M reflective material for the best night time visibility. - Perfected since 2002, our design uses thin military spec nylon webbing which is approximately half the thickness of others. - The collar is decorated with durable polyester grosgrain ribbon that is easy to clean. - All hardware is durable metal for years of use. - Backed by the If It Barks warranty that if the stitching or hardware fails with regular wear, we'll replace it. - Handmade in North Carolina. - 1.5 inches (3.8 cm) wide in sizes small (11 - 15 )(28 - 38cm), medium (15 - 22 )(38 - 56cm) and large (19 - 30 )(48 - 76cm) Measure Your Dog: Loosely measure the neck where the collar would normally sit sliding two fingers between the dog's neck and measuring tape. Measure the widest part of your dog's head. Order a collar that will fall within the range of these measurements. Care Instructions: If It Barks collars are machine washable. We suggest placing the collar in a pillowcase or lingerie bag to protect metal hardware.
