Measuring you dog for a Roadie™Elite Restraint Seatbelt

dog measuring fig

To get the RIB CAGE CIRCUMFERENCE measure your dog around the LARGEST part of his/her rib cage just behind the front legs while your dog is standing.

The "Two Finger Rule"
You should be able to insert between two and four fingers vertically between the bottom of the harness (where lead attaches to harness body) and the dog's back - less than 2 fingers, too small - more than 4 fingers, too big.

This size chart is an approximate guideline for sizing your dog.

Puppies need to be sized just like full grown dogs. We do not recommend that you buy a size larger for your puppy so that they will "grow into it". If the harness is too big it will fall off.
