Pittsburgh Steelers pet jersey - PREMIUM size MEDIUM. This great-looking jersey features applied throwback team logos on the sleeves, team name/logo on the back along with a sewn "Property Of" size tag where you can write your pet's name on. The jersey has an updated look and feel - more like an actual player jersey - quality mesh, with satin-like accents on the shoulders/sleeves and down the sides! Cut shorter on the front belly area. Made of 100% polyester - hand wash. Approximate sizing(a size medium or large for example doesn't necessarily mean for a "medium" or "large" dog). Be sure to measure ALL AREAS of your pet to best avoid having to return. NECK - measure neck around. LENGTH - base of neck to base of tail. GIRTH - the chest at widest point, which is usually behind the front legs. Comfort levels may vary with each individual dog. Officially licensed by the NFL. A great item for the fan and their pet.
