Size Guide
All dogs are different, that's why we have multiple sizes. Our collars and harness are easy to adjust based on your dogs size. We recommended sizing your dog's neck, chest and girth with a measuring tape before adding your collar, leash, harness and bandana to your shopping bag.


We recommend a smaller leash for dogs under 20lb, the small leash is more lightweight and a little shorter. All leashes have three attachment points to way them in multiple lengths and ways.

Collar & Leash Sizing
How to Measure Your Dog's Neck
Use a flexible measuring tape and wrap it around your dog's neck where the collar would sit. You should be able to fit two fingers between the tape and your dog's neck for a comfortable fit. If you don't have a measuring tape, use a piece of string and measure it against a ruler.

Harness Sizing
How to Measure for a Harness
Measure the widest part of your dog's chest, just behind the front legs. Make sure your dog is standing in a natural, relaxed position. The tape should be snug but not tight — you should be able to slide a finger underneath.

Choosing the Right Bed Size
Measure your dog from nose to tail while they're sleeping in their natural position. Add a few inches for comfort. If your dog likes to stretch out, consider sizing up. If they prefer to curl up, the standard size recommendation should work perfectly.
