What you'll need:
A soft tape measure
A calm dog (treats help!)
A friend to assist (optional, but handy!)

You will need to measure your dog's chest girth. 

Chest Girth (Widest Part of Rib Cage):

Find the widest part of your dog’s ribcage—usually just behind the front legs. Wrap the tape measure around this area to get the chest girth.

Tip: Keep the tape snug but not tight. You should be able to slip one or two fingers between the tape and your dog’s body.
