Measuring your pet is easy. Make sure your dog or cat is standing squarely on all four paws. If necessary have someone help you. Use a soft sewing tape measure or a string.
Take each measure a few times to make sure you have the right measurements. Follow the diagram below and measure your cat or dog as shown.
For the fabric Harnes vest and or my Canine Cozy Coat measure about 3-4 “behind your pets front legs.
