ComfortFlex Martingale Collar for Dogs - American Made Slip Collar, Reflective, Adjustable, No Pull Training Collar for Medium Dogs – Soft, Wide, Fully Padded, Escape Proof - Medium, Red

The comfortflex limited slip collar is designed to keep your dogs both safe and comfortable on their walks. The lightly padded nylon collar goes on loose, easily slipping over the dogs head. If the dog pulls in any direction away from you, the collar then tightens down enough so that the dog can not slip out of the collar, but not enough to choke the dog. The highly reflective strapping makes this collar very easy to see in low light situations.
