Size Guide
Unsure about the size? No problem! As collar and lead sizes can vary between brands, we've put together this handy guide to help you find the perfect fit for your pup.
How to measure your dog for a collar
Simply wrap a soft measuring tape around the widest part of their neck, just below the ears. Make sure it's snug but comfy, leaving enough room to fit two fingers between the tape and your dog's neck.

CHOOSING THE RIGHT LEAD
