Choose according to your dog’s chest measurement, body shape and intended use. Slim Fit suits smaller and lean-framed dogs, Regular Fit suits many active medium-to-large companion dogs, and the 48 mm Heavy Duty design is intended for powerful dogs and demanding training or working environments.

The Regular Fit is a practical starting point for many Staffies because it provides four-point adjustment for their broad chest and relatively compact waist. A Staffy involved in protection sport, working activities or particularly demanding training may be better suited to the Heavy Duty version. Always confirm the choice using your dog’s actual measurements.

No. Rogue Royalty states that SupaTuff® harnesses use double-pin stainless-steel roller buckles rather than plastic side-release clips. Their D-rings and O-rings are also made from stainless steel.

The harness should be snug enough to remain centred and prevent your dog from easily backing out, but it should not restrict breathing, shoulder movement or front-leg movement. Check for rubbing behind the legs and make sure the straps are lying flat rather than twisting or digging into the coat.

Wash the harness with warm, soapy water and allow it to air-dry completely. Periodically inspect the webbing around the roller buckles, D-rings and other contact points. Stop using the harness and replace it if significant fraying or structural damage becomes visible.

Yes. SupaTuff® harnesses carry a lifetime guarantee, which refers to the lifespan of the dog and covers manufacturer faults. Damage from chewing, rubbing on hard surfaces or beach use is not covered. Full terms are on our guarantees page.

Yes. Comfort padding is available for each fit: Slim Fit, Regular Fit and Wide Fit. Choose the padding that matches your harness fit.
