Shop by Size

Wag Theory jacket sizes are categorized by length from base of neck to base of tail.

Plus there are two other important measurements (neck and chest) to ensure proper fit. Each in-stock product listing will have all three measurements listed.

Average breed guidance is offered below but it is always best to measure your pup before purchasing your jacket, as dog bodies come in all shapes and sizes, just like people do!
