Medium breeds have the widest variation in body shape of any size category. A Staffy and a Border Collie can weigh the same, yet differ in chest depth, neck circumference, shoulder width and the way they walk. The harnesses in this collection cover that whole range, from lightweight everyday designs to heavy-duty builds for dogs that pull hard.

Active X harnesses are designed for everyday use on active medium breeds. They are made from lightweight, water-resistant materials with soft, breathable padding and a chest support panel designed to help prevent rubbing behind the front legs. The straps adjust on all sides, and a backstrap handle and reflective strips add control and visibility. Choose from Black, Pink, Green and Sahara. Active X is a practical everyday choice for medium companion breeds that walk consistently without extreme pulling.

The SupaTuff range is built for medium breeds that pull hard. The SupaTuff Regular Fit uses 40 mm double-ply nylon webbing with stainless-steel fittings and no plastic buckles, and it is weather and water resistant. For Staffies, Bull Terriers and Australian Cattle Dogs that put real force through a harness on every walk, this is the construction that matches the load. The SupaTuff Slim Fit brings the same double-ply webbing and stainless-steel hardware to leaner medium breeds and growing adolescent dogs, in a narrower 25 mm strap. For strong, active and working dogs that need a wider, more supportive fit, the SupaTuff Heavy Duty Wide Fit uses a 48 mm double-ply strap.

Quick Fit harnesses are made for fast, easy fitting. They have a click-and-go design, a knitted outer, a padded ventilated mesh interior and fully adjustable chest and girth straps, which suits medium dogs that wear a harness every day and owners who want to get out the door quickly.

The Attila leather harness is the premium end of the collection. It is made from premium grade bridle leather with 100% solid brass fittings and buckles, adjustment points on the top, bottom and both side straps, and a large, fully padded front chest piece. It is available in Black and Brass and Brown and Brass, and suits owners who want craft and durability in one piece.

Whichever style you choose, a harness that adjusts around both the chest and the girth makes the difference on medium breeds with unusual body proportions. It is what keeps a harness from rotating or shifting after the first ten minutes of a walk.

Active X for everyday active dogs: if chafing behind the front legs has been a problem with previous harnesses, or your dog has a short, fine coat that shows friction marks easily, Active X is a good starting point. It is the lightest of the options, and its padded chest support is made for dogs that move constantly on walks. Border Collies, Kelpies, Spaniels and similar active companion breeds suit it well.

SupaTuff for consistent pullers: Staffies, Bull Terriers and Australian Cattle Dogs put more force through a harness than most medium breeds. The double-ply webbing and stainless-steel hardware of the SupaTuff harnesses are built for that load, so it is the more durable long-term choice if your dog pulls on most walks regardless of training. For larger breeds such as Rottweilers and German Shepherds, see our large dog harnesses. Read our guide to the best harness for strong dogs for a detailed breakdown.

Quick Fit for everyday ease: choose Quick Fit when speed and comfort matter most. The click-and-go fit makes it quick to put on, and the padded, ventilated mesh interior suits everyday walks.

Leather Attila for craft and premium positioning: the Attila suits owners who want a harness that works as a daily piece and a statement of quality at the same time. It handles normal daily walking and moderate activity well. For dogs that swim regularly, spend extended time in mud or generate extreme pulling force, a SupaTuff nylon harness is the more practical material choice.

On soft harnesses for medium dogs: owners searching for a soft harness usually want something lighter and less restrictive than heavy-duty gear. Active X, with its soft, breathable padding, and Quick Fit, with its padded mesh interior, are the closest options in this range.

Staffies create more harness fitting problems than any other medium breed. Their deep, barrel-shaped chest is wide relative to their neck, and their waist is much narrower than their chest. A harness with a single adjustment point can rotate and shift on a Staffy, so look for one that tightens around the chest and the girth independently. That is what keeps the fit correct during an active walk.

For powerful medium dogs in everyday companion use, the SupaTuff Regular Fit is the practical recommendation. For especially strong Staffies, or those working in demanding environments, the SupaTuff Heavy Duty Wide Fit is the better match. Measure chest girth specifically, because it varies considerably between show-type and working-type builds. For mastiffs and Cane Corsos, see our large dog harnesses.

Cattle Dogs are athletic, dense and deceptively strong for their size. The SupaTuff Slim Fit suits leaner, adolescent Cattle Dogs, and the SupaTuff Regular Fit suits adult Cattle Dogs with a broader chest. Measure before ordering rather than guessing by weight.

These breeds are medium in weight but lean in build, with relatively narrow chests. They suit Active X for hiking, trail walking and active outdoor use. The padded chest support helps keep the harness stable through the constant changes of direction these breeds make during off-lead play, without the bulk of the heavy-duty range.

Girth is the primary measurement: the circumference around the widest point of the chest, just behind the front legs. Rogue Royalty harness sizing is based on this number, not on weight or breed, and a Staffy and a Cocker Spaniel of similar weight can differ by 10 cm or more. Measure snugly with a soft tape, then match it to the size chart on the exact product page. Our dog size guide walks you through it.

As a guide, the Medium size in each range fits these girths:

• SupaTuff Regular Fit: 53–70 cm
• SupaTuff Slim Fit: 53–69 cm
• Quick Fit: 59–87 cm

Each style is sized differently, so always confirm on the product page. When between sizes, take the larger option and adjust the straps.

For medium breeds that pull consistently on lead, using a harness as the main lead attachment protects the neck and throat from the sustained pressure of collar-only walking. A collar still has a job to do: it carries the ID tag. The harness takes the walking load. This setup suits Staffies and Bull Terriers, whose strong necks can tolerate collar pressure but whose tracheas are still better off with chest pressure that is spread out. Browse our dog collars and dog ID tags to complete the set, or read the harness vs collar guide for the full breakdown.

Medium dogs that are new to wearing a harness often resist the fitting process. Introduce the harness indoors over several days with treats before adding a lead outdoors. A harness that requires force to put on is either the wrong size or the dog hasn't had enough time to accept it. Read thestep-by-step fitting guidebefore the first use.
