When measuring the chest: Be sure to measure around the widest part of your dogs chest - a couple inches behind the front legs!
When measuring the neck: Be sure to measure around the widest part of your dogs neck - at the base where the harness will sit, not where a collar sits!
If your pup falls between sizes or they are still growing or filling out, we recommend sizing up!
*Heads up! Our harnesses have updated! The new versions will have openings where the strap meets the chest and back panels to tuck in the excess strap tails. If it doesn't reach, just move the tri-glide slider towards the end of the loose strap to hold it down.
