Our top tips for harness and collar sizing:
  • We recommend measuring your pup using the size guides below for the PAWfect fit!
  • If you can't measure, use our handy ambassador photos at the bottom of this page and remember we accept returns and exchanges if needed!
  • If your pup is between size brackets, we recommend sizing up, especially if they have more growing to do.
  • New puppy?! We recommend starting them off in a harness as soon as possible to get them used to wearing one before the post jab walkies. Our XXS and XS sizes are PAWfect for new pups!
