Sizing Tips

  • Find your jacket size based on pup's BACK LENGTH first, then check that the girth and neck ranges are sufficient.
  • Back measurement is taken from the back of their neck to the base of their tail.
    Girth measurement is taken around the biggest part of the rib cage while standing up.
    Neck measurement is taken around the base of the neck.
  • If you need extra length around the Girth or Neck, add a note of your pup's measurements to your order to request extension straps. Email us if you're unsure.
