ACG FlyHarness - Ultra Lightweight & Breathable Dog Harness with Reflective Strips for Small Medium Large Dogs - Perfect for Hiking, Running & Night Walks

Love this harness. For reference I ordered size 5. My dog’s chest size is 30 1/2 and neck is 17 inches.I could have gotten a size 4 but took my chances and ordered a bigger size since the neck part was adjustable and you can cut it if it’s too long per instructions given. I’m so happy with my order and it fits great! Even Luna got excited wearing it!Our dog backs up and easily slips out of it in seconds. Harness looks amazing on our dog, but does not look nearly as amazing off our dog when I'm running down the street with the harness dangling from my dog's leash in my hands as I'm chasing after my escaped dog.Fits great I got a size 3 for my 55lb Staffordshire. It got on the biggest setting. I got a 2 for my 25lb lhasa apso, it fit on the smallest setting. I love the look, very clean cut and it's not bulky.I’m glad that I made the purchase on Amazon not Zeedog, because otherwise I probably wont be able to return this harness. It looks exactly like the pictures. The material (especially chest strap) is extremely stiff. It was also a very weird fit for our dog (Shiba inu) - too low it limits his walk, too high it starts to chock him. I cannot recommendCovered in hair and completely filthy. My dogs harness, which he has had on for a year is way cleaner. Joke. Disgusting in a dirt way and in a service way. Do better.Bought the 2 & 3 sizes. Her girth measurement fits within both those sizes per their chart and the straps are adjustable BUT neither fit my 45-pound dalmatian. When I asked customer service for extra buckles (to make my own extender) they rudely told me they will not provide those. Skip this harness and brand, its not worth the money for the hassle it provides you.Very disappointed. This is the wear on the harness I received about 4 months ago after jogging daily with my 27lb puppy. For the price I expected it to last at least a year. The stitching is extremely weak.Very Unsafe and if your dog pulls even slightly in the opposite direction they can escape easily.Perfect harness for my dog. Very convenient and easy to use.
