Sizing Guide

Find the Right Fit

Quick sizing help for collars, leashes, hands-free leashes, and tug toys.

01 / COLLARS

Collar Sizing

Take a flexible tape measure around the center of your dog’s neck where the collar naturally sits. You should be able to comfortably fit two fingers underneath.

Your dog’s neck measurement should be the middle of the collar size range. Example: If your dog measures 19", choose an 18–20" collar.

02 / STANDARD LEASHES

Standard Leash Sizing

Measure from the bottom of your foot to the top of your shoulder. This is your recommended standard leash length.

Want your dog closer? Size down slightly. Want a little more room? Size up slightly.

03 / HANDS-FREE LEASHES

Hands-Free Leash Sizing

Measure around your waist or over your shoulder depending on how you wear the leash. Then measure from the middle of your stomach to where your dog normally walks.

Body measurement + dog walking distance = ideal end-to-end leash length.

04 / TUG TOYS

Tug Ball Sizing

Ball size depends on your dog’s size, bite style, and play preference. Weight is a great starting point.

Tug toys are not chew-proof and should always be used with supervision.
