Kitten & Puppy Harness and Leash Set Size Chart


Specifically sized for kittens and extra‑small breeds
Keep your tiniest friends safe, comfortable, and stylish on every stroll with our step‑in harness and matching 4 ft leash—designed especially for extra‑small dogs and kittens.
After a painful tug left both Will and his dog injured, he partnered with veterinarians and behavior experts to create the AutoBrake Leash. Drawing on car seat‑belt technology, it gently slows sudden lunges, protecting your dog’s neck and your arm. After three years of real‑world testing with hundreds of dogs, FIDA gear has earned the trust of trainers and thousands of pet families—making every walk safer, more controlled, and more enjoyable.
With over 30 years in pet‑safety R&D, manufacturing, and sales, FIDA has helped millions of dog owners upgrade their walking experience.
We believe every walk with your pet should be safe, comfortable, and enjoyable.
