Today may have included some questionable decisions. Maybe something got shredded. Maybe a rule was ignored. Maybe your dog simply woke up and chose chaos.
But yesterday?

Sizing Information
Please do not rely solely on weight ranges when selecting a size. Dogs come in many shapes and proportions, and two dogs of the same weight may require different sizes. For the best fit, please refer to our size chart before ordering.
