For length: measure from the base of the neck to where the tail starts (or the base of the tail)...
For girth: measure around the doggie at its thickest which is usually just behind the front legs...
If you can get a tape measure and give us these measurements, we can be sure to send you what you need and then your little one will have a regular wardrobe!
Please place the length and girth measurements here on this thread.
We'll take care of Prince. After you add the measurements on this thread, please PM your address to me. I'm certain I have some things.
