PAWSnCLUBS - Designer Pet Apparel Smokie the Dragon Dinosaur Costume Please note that this listing is for EXTRA LARGE size - 12" Body Length, 22" Breast Girth and 16" Neck Girth. We recommend one size up for comfort if your dog's measurement is the higher end of the range listed. Sizing for each dog is unique. Similar to our clothing and accessory, medium size from one designer is not the same for another. For example our 9-pound yorkie model usually fits either one of three sizes (i.e. XS, S, M) depending on the designer. We highly recommend you measure your pet precisely with a flexible tape measure to ensure the best fit. Contact us if you have question. We are happy to help. This Smokie the Dragon Costume Costume is just a perfect gift for your little one! You will not be disappointed with the details. Easy to put on and comfortable to your little baby. Super cute reflective wings at the back.
