Martingale Style CollarsMartingales are for dogs, and their owners, that prefer a gentle, non-pulling collar when they walk on a leash. This style is especially useful with dogs that have larger necks and smaller head (e.g. pugs). Martingale collars do not come with a side-release buckle, they slide over your dogs head; therefore, the collar must be large enough at its maximum adjustable size to slide over the widest part of your dog's head.
 
Please note:
Martingale collars should never be left on dogs without supervision.Diva-Dog adjustable dog collars are made of soft and comfortable nylon overlaid with durable polyester ribbon, which is quintuple stitched at stress points for added strength. Exclusive design by Diva-Dog - Made in the USA l
