Sizing guide

Get the right fit.

Four simple checks to measure your dog with confidence before you order.

How to measure your dog

  1. German Shepherd having its neck measured with a soft tape
    01

    Measure the neck

    Wrap a soft tape around the widest part of the neck, where the collar will sit.

  2. German Shepherd with a measuring tape around the deepest part of its chest
    02

    Measure the chest

    For harnesses, measure around the deepest part of the chest, just behind the front legs.

  3. Side view showing the correct position of a measuring tape around a dog's neck

    Where the tape sits

    Keep the tape flat and level — not twisted, and not too high behind the ears.

  4. Two fingers placed beneath a measuring tape around a dog's neck

    Two-finger check

    You should be able to slide two fingers flat between the collar and your dog's neck.

Choosing the right kit

Collar widths

Wider collars spread pressure across the neck and suit larger, stronger dogs; narrower widths suit smaller breeds and puppies.

Lead types

Fixed-length leads give consistent control for walking; longer lines suit recall and training work.

Puppy sizing

Puppies grow quickly — check fit weekly and choose adjustable options where available.

Training equipment

Choose training equipment for your dog's needs and use it with guidance from a qualified trainer.
