Where to measure
Go around the middle of the neck, where a collar naturally sits. Not up behind the ears, and not down at the shoulders.
1
Measure
Wrap a soft tape measure around the middle of your dog's neck, where the collar sits.
2
Add two fingers
You should fit two fingers flat under the tape. That's your neck size.
3
Pick the middle
Choose the size where your number lands near the middle of the range, so there's room to adjust.
