Size Guide
Welcome to our Size Guide! We created this page help you find the most ideal collar size for your pet. Keep in mind, all collars are made-to-order and sales are considered final. Please don't guess your pet’s measurements!
You can get a soft tape measure at any craft store/big-box retailer, you can buy one online, or you can print one out and tape it together. Please do not use a hard tape measure.
Any confusion? Send us an email with any questions or to confirm sizing. We’re happy to assist! hello@hypnoticdog.co
