Guide & FAQs

Prong Collar Fit Guide: How Many Links Do You Need?

Unlike flat collars that are adjusted via a buckle, prong collars require you to physically add or remove metal links to achieve the correct size. The required number of links depends entirely on the thickness of the wire (the gauge) and your dog’s specific high-neck measurements.

Measuring High Neck Circumference Safely

To use the calculator, you must measure your dog’s neck correctly. Do not measure the base of the neck where a standard collar sits. Instead, use a soft measuring tape to measure the circumference high up on the neck, directly behind the ears and under the jawline.

Frequently Asked Questions

Where should a prong collar sit on a dog’s neck?

For a safe, dominant fit without choking, a prong collar must sit high up on the neck, directly behind the ears at the base of the skull. The number of links needed is your dog’s high-neck circumference divided by the link gauge length.
