The ComfortFlex Limited Slip Dog Collars are designed to keep your dog both safe and comfortable on walks.

They are easily adjustable and lightly padded nylon collar that goes on loose and easily slips over your dog's head. Like all martingale collars, if your dog was to pull away from you in any direction, the collar tightens enough so that your dog can not slip out. But unlike other collars, it is limited so it can not tighten enough to choke your dog.

It also features reflective strapping so your dog can be seen in low light situations. Not for use with tie outs.

Machine washable. Made in the USA.
