The Signature PerfectFit 3-piece Harness
At PerfectFit, almost every harness we fit is built around our signature 3-piece modular design and for good reason. This isn’t just a harness; it’s a system that allows us to create a truly custom fit for dogs of almost any size, shape or age from tiny pups to longer-bodied breeds or deep-chested adults.
Why 3 pieces matter
Most traditional harnesses are made in fixed sizes that may fit broadly, but they rarely fit perfectly. The PerfectFit Harness solves this with three separate pieces: a top, front, and girth. Each of these pieces comes in a variety of sizes, which can be mixed and matched to fit your dog’s unique body shape. This modular design makes the harness especially ideal for growing puppies and dogs with unique proportions who struggle to find a perfectly fitting harness elsewhere.
The Top, the Front & the Girth
Stylish and secure comfort
The top piece comes in a variety of colours, and sits across the top of the shoulders on your dog's back to allow full freedom of movement and a comfortable, secure fit.
Optimal adjustment
The front piece sits on your dog's breast plate, down the chest, and has up to 3 areas of adjustment to help prevent twisting and keep the harness balanced and stable.
Flexible sizing
The girth piece wraps around the ribcage to provide security, plenty of adjustability, and a snug, escape-resistant fit
Size Collections
Our 3-Piece PerfectFit Harness is designed to fit dogs of all shapes and sizes, from small and medium sized breeds, up to large and giant dogs.
Designed for health, comfort and safety
The PerfectFit 3-piece Harness features a Y-shaped front that distributes pulling force evenly across the chest, keeping pressure off the throat and neck, a benefit recognised by vets, trainers and behaviourists alike.
The pieces are easy to clip around the neck (no wrestling the dog through), adjustable in multiple places, and can be replaced individually if needed. This makes the harness long-lasting and adaptable, strong enough for everyday walks, yet soft and calming enough that many dogs walk as if they’re free.
