Dear Human, I have worked with the finest furry tailors in the world, and am here to share my bounty of knowledge. Here's how to measure your pet... Length Measure from the base of the tail (where it connects to the hindquarters) up to where the collar typically sits at the base of the neck, then follow up with a generous back scratch. Chest This is measured by giving your pet a hug, during which you measure the entire circumference (all the way around) at the widest point of your pet's chest. This is typically right behind the front legs. Neck First, plenty of kisses. Then, measure the neck's circumference (the distance around it) at the point where the collar sits.

Important Sizing Note: The following measurements are the dimensions of the actual product, not of the pet they fit. After measuring your pet, make sure all measurements fit within the following dimensions (with a little room to spare in the chest and neck).
