How to measure
-
Find the spot
The collar sits around the middle of the neck — below the jaw, above the shoulders. Measure there, over the fur.
-
Wrap and measure
Use a soft sewing tape. No tape? Wrap a piece of string, mark where it meets, then lay it flat along a ruler.
-
Snug, not tight
Keep the tape flat against the coat without squeezing. Round to the nearest quarter inch.
-
Match the range
Choose the size whose neck range includes your number. If two sizes overlap, pick the one where you sit nearer the middle — or size down for a snug, secure fit.
The two-finger rule
Once the collar is buckled, slide two fingers flat between the leather and your dog's neck. A little resistance is right. Can't get two fingers in? Loosen a hole. Room for three, or does it slip over the ears? Tighten a hole, or exchange for the smaller size.
Breed suggestions
A starting point only — every dog is different, so trust the tape measure over the breed.
