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 neckline. 

Neckline (Base of Neck):
Wrap the tape measure snugly around the base of your dog’s neck—where the neck meets the shoulders, not where a collar usually sits.

Tip: Think of where a polo shirt collar would naturally sit on your dog. Don’t measure too high.

Measuring Tips for Best Results:
Keep your dog calm and standing upright. Ask a friend to help and use treats or toys to keep them relaxed.
For fluffy dogs, part or gently press down the fur to get an accurate measurement close to the body.
Measure more than once to make sure your numbers are consistent.
