Happy Puppy Designer Dog Apparel - Reversible Striped Denim Jacket - Color: Red, Size: M For sizing chart, click on the other images link above. We recommend one size up for comfort if your dog's measurement is the higher end of the range listed. Please note that these lengths represent the size of the dog and do not reflect the actual length of the garment. 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. Fashion meets warmth for the upcoming season. Reversible denim jacket for a two-way look. Dark-washing Denim. Functional pocket at the bottom. Convenient leash hole at the back perfect for everyday walk. Practical, functional, and stylish all at the same time. Comes in Red and Blue.
