Alfie Pet Apparel - Reni Waterproof Camouflage Raincoat for Dogs Please note that this listing is for Medium size - neck girth: 12.5", breast girth: 16", body length: 11.75" . 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. Who says functional raincoats can't be cute? Easy to put on and comfortable to your little baby. Made of superb quality waterproof material that is soft and comfortable. Functional pocket at the back and two reflective stripes around in front and waist-line for extra safety for walks at night. One of our favorite picks for rainy season.
