How to Measure for the Perfect Fit
Please do not measure your current collar.
Do not guess the size.
Only a snug, precise measurement ensures a perfect fit.
1. For Martingale & 'O'-ring style collar:

Martingale and ‘O’-ring collars are both slip-style collars, designed to slip easily over the head, yet stay secure when your dog lowers its head.
To measure:
Wrap a soft measuring tape around the widest part of your dog’s head, just in front of the ears — the tape should be SNUG, not loose👇
You should still be able to slide the tape over the head and down to the neck without adding extra centimeters.
We craft our collars with ample built-in comfort. If the tape is too loose, the final collar will be oversized.
If your dog’s neck and head are nearly the same size, measure both and use the larger measurement.
2. For Buckle style collar:
Using a soft measuring tape, measure around the middle of your dog’s neck — where the collar naturally sits — as shown in the image below. 👇
Please measure your dog’s neck snugly and accurately, with the tape resting close to the skin—not loose and without adding extra space. Measuring with the “two fingers” rule often results in a collar that’s too large.
We design each collar with generous ease for your dog’s comfort, so there’s no need to size up. Trust the snug measurement for the perfect fit.
