How to measure & determine the size you need for a Slip-On Martingale or Half-Check collar (slips over the head):
- Measure 1) the largest part of your dog’s head, and 2) the middle of his/her neck.
- If your dog’s head is larger than its neck, you will use your dogs head measurement to determine the size you need.
- If your dogs neck is larger than his head, you will use your dogs neck measurement to determine the size you need.
