AVA martingale is an
limited-slip collar that is 100% water and odor proof with a quick-release cobra buckle for security. This training collar
prevent dogs from slipping out and communicates by constricting when the dog pulls on the leash.
SIZES LISTED ARE FOR REGULAR NECK MEASUREMENT
The sizes listed are based on the measurement you would use when purchasing a regular collar. Room is already added for the martingale loop.
If you want to provide extra room or if your pup is used to a looser fit, we will suggesting sizing up by 1".
** The loop should not completely close when the collar is fitted properly and will always have a minimum of 1-2" gap based on size and breed variation.
Tension on the leash causes the smaller loop to tighten, which in turn pulls the larger loop tighter.
