How to Fit a Collar (for all breeds)
To measure your dog for a Martingale Collar, use a soft tape measure and measure three points
1) around the widest part of the head
2) behind the ears
3) around the neck (where the collar will sit).
As this is a slip-on collar, you should allow at least 2 inches larger than the widest head measurement to slide the collar on and off comfortably.
When sizing for breeds that are not sight hounds, please take the measurement around the widest part of your dog’s head.
