PRODUCT DETAILS

Overview

Select the appropriate size and connection option for your dog. The black surface can gradually develop an antique appearance through friction and may mark very light coats. Use only for supervised, on-leash training; remove for off-leash activity and crating. New users should seek fitting and handling guidance from a qualified trainer.

SIZE, FIT & CARE

How to Choose the Right Size

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
