Witzig dog choke-free harness made specifically for Dachshunds! ITEM DETAILS Fitted to prevent pressure on your dachshund's trachea or windpipe Crafted of lightweight, cooling mesh, with strong and durable velcro Machine washable SIZE GUIDE To determine the best size for your dachshund, measure their chest just behind their front legs, and add an inch to allow for comfort. If the pet can tuck its head and back out, the harness is too large and a smaller size should be selected. XS: 11" - 12" S: 13" - 14" M: 15" - 16" L: 17" - 18" XL: 19" - 20" XXL: 21" - 22" Always remember that each and every doxie is unique and, as such, we recommend trying their harness in an enclosed environment before using it outside. Please note this harness may run smaller than you're used to - it is important to measure your dog in order to ensure the correct fit. The size guide below will provide helpful direction, but if you have any additional sizing or measuring questions, please reach out to our team at help@witzig.com and we will be happy to assist you!
