Matte Stainless Steel ClicLock safety fastener with D Ring

01 Measure your dog

Use a soft tape or string. Keep it snug with room for one finger; do not pull tight.

Neck

Prong: high behind the ears, below the jaw. Chain and everyday collars: where the collar will sit.

Head

For any slip-over collar, also measure the widest part of the head. The opening must pass over it comfortably.

02 Choose by collar type

Prong collars

Choose the gauge first. For assembly-chain models, start with high-neck measurement + about 2 in; add or remove matching links for a snug fit.

Slip-over chain collars

Fur Saver: neck + about 2 in. Assembly-chain styles: neck + about 3 in. Always check head clearance.

Neck Tech

Without assembly chain: use neck size. With assembly chain: add about 2 in. Adjust with compatible elements; measure high for training use.

Buckle, hook & BioThane

Use neck size and the listed fit or adjustment range. A stated chain length may include end rings and is not the usable neck size.

03 Select the wire gauge
