Martingale Collars with Chain Loops
Martingale Collars with chain loop (also known as 1/2-checks or half-checks) offer the safety of a martingale and the sound needed to get your dogs attention for voice command training. The action of the chain in a half-check collar is smoother and quicker, thus making leash training easier. It is also a good collar and will wear much longer if you have a dog that constantly pulls on leash.
