Discover our collection of small dog and Chihuahua harnesses, leads and collars, with tiny sizes specially selected for puppies, toy breeds and smaller dogs.

Our own Tiny Trails step-in harnesses start from XXXS, making them ideal for tiny Chihuahua puppies and other little dogs that can be difficult to fit. Choose from lightweight breathable air mesh, cosy faux-fur lined styles and a range of colours, with matching leads available.

Designed with comfort and fit in mind, our step-in harnesses are easy to put on without going over your dog's head, with generous leg openings and secure fastenings for comfortable everyday walks.

Alongside Tiny Trails, you'll find a carefully selected range of small dog harnesses, leads, collars and matching sets from leading brands including Puppia, Urban Pup, Julius-K9 and PerfectFit.

Whether you're looking for a first puppy harness, an everyday walking set, breathable mesh for warmer days or something cosy for colder walks, you'll find options designed for little dogs and growing pups.

Finding the right size
A well-fitting harness should be secure without restricting movement or rubbing. Always measure your dog's chest and neck rather than choosing a size based on breed or weight alone.
