LA Dog Sizing Guide (Standard Buckle and Martingale)
Measuring an old Buckle collar: If you are satisfied with the fit of your dog's current collar, measure that collar from the center bar of the buckle to the farthest hole. Our collars are sized according to this measurement, not to the overall length of the collar, which varies by manufacturer and by whether it is a buckleend or a deeend style collar. (see diagram below):
Measuring you dog's neck: For a standard buckle collar, the collar size is approximately the distance from the center of the buckle to the last hole. To calculate the correct collar size, take the exact (comfortable) measurement around your dog's neck and add 2".
This is the collar size you need.
For a Martingale collar, the collar size is approximately the distance around the collar at its widest opening. To calculate the correct collar size, take the exact (comfortable) measurement around your dog's neck and add 2".
This is the collar size you need.
Examples:

If your dog's exact (comfortable) neck measurement was 12", you would add 2" and pick a collar size closest to 14". This would be the size 14 collar.

If your dog's exact (comfortable) neck measurement was 15.5", you would add 2" and pick the collar size closest to 17.5". This would be the size 18 collar.

If your dog's exact (comfortable) neck measurement is exactly in between two sizes, then pick the smaller size. The collar will stretch slightly with wear.
