Sleepypod Locking Martingale Collar

This collar is very effective training tool. I put it on my yorke for 5 minutes and after a walk outside, he learned to stop and measure the distance of the leash. Very adjustable collar too. Ive been looking for a collar like this for a while and it is very well designed. I love the color and how easily the collar makes connecting the leash possible.

Too big but nice quality

The small was too large for my dog - she has a small neck but I thought it would adjust to fit - definitely only works for 11" circumference and larger for this collar.
