And it won't cause her to choke or anything like that." - Alyssa P. & Bella "This is a really great harness. I would highly recommend it. It has all the features we're looking for. Good for an active lifestyle or a non-active lifestyle" - Cassidy L. & Koa "We love all the Comfort X series because of the x frame design. It protects them from neck injuries and tracheal collapse, which is so important for small dogs and brachycephalic breeds." - Hana S. & Pepper "The rotational buckle is absolutely a key part of this harness. It's probably one of my favorite details. It's so easy. My grandma's actually having to film holding it, and she's having such an easy time doing it." - Jen F. & Louie "The most important feature for us is the escape free mechanism, which lightly tightens around the abdomen when being pulled, which provides security and peace of mind." - Jayla M. & Jarvis "It's a very, very good quality material, very lightweight, and just super comfortable for her. And it has made such a difference in our family walks." - Bethany S. & Hercules and Lily How does this harness differ from other Gooby harnesses? In the past, Gooby harnesses either had the Escape Free or the Choke Free feature, but never both. Escape Free Comfort X One is the first Gooby harness that has both. Is the Comfort X One harness suitable for all types of dogs? It is suitable for most toys, small, and medium sized dogs. It comes in a range of sizes from dogs with chest measurement of 10.5" up to 33". How do your sizes work? Our sizes run small since our harnesses focus on small to medium sized dogs. Please take a look at our size chart for more information and how to take accurate measurements. How do I measure my dog for the correct harness size? Measure around the widest part of your dog's chest, just behind the front legs. Do you have it for dogs with a chest size smaller than 9”? No we don't. The smallest chest size starts at 10.5". You can check the sizing chart provided per Gooby product to determine the best fit for your dog.
