Bad to the Bone Studded Tee has an edgy appeal for dogs that walk on the wild side. Jet Black shirt is trimmed with white stitching at neck and cuffs. White Bad to the Bone logo with pawprints topped by silvertone studs give this tee real attitude. Made of machine washable 100% cotton jersey knit. Available in X-Small (fits back length up to 8") and Small (fits back length 8"-12"). Measure length of pet's back from the base of the neck to the base of the tail. If the measurement is between sizes, we recommend going up one size. Also, if pet has a stout build, a deep chest, or is overweight, we recommend going up a minimum of one size for proper fit. If the dog is long-backed, like a Dachshund, a smaller size is recommended.
