EzyDog Checkmate Martingale-Style Dog Collar
The EzyDog checkmate collar is a martingale-style correction collar that does not require the act of re-sizing for each fitting. So with all the time you just saved, you can spend it correcting your pup's unwanted behavior while on a leash. Just give a tug and the low profile nylon collar with reflective stitching, and it will cinch up to let him know that you're checking. (do not leave the collar on your pup unattended.)
