What is a Martingale Collar? Martingale
Collars have 2 loops. The smaller of the loops is called the "Control
Loop". This is the portion of the collar that is attached to the leash
and tightens when it is pulled. The second loop is the adjustment loop.
This is the part of the dog collar that you adjust to the right size to
fit your dog.
Dog trainers use martingale collars because of the
gentle choke. Martingales are much more humane then a choke chain. For
this reason Martingale collars make great training collars for all
breeds.
