Top Paw Martingale Dog Collar size: Small, Black

No-slip, adjustable, nylon choke collar for training purposes. No-slip, adjustable-choke collar is an excellent solution for dogs, such as greyhounds, who slip out of their collars. Ideal for training, its limited closure prevents the choke from becoming too tight. Not intended for use as your dog's primary collar. Do not attach I.D. tags or leave on your dog unsupervised. If you have questions about the proper use of the Martingale No-Slip Collar, please consult a professional trainer.
