A harness should offer a secure, adjustable fit for everyday outings without getting in the way of movement. This Hamilton design is intended for daily walks, training sessions, and active play, with flexibility and control for your dog. Its black nylon construction makes it a straightforward choice for pet owners looking for a harness that can be paired with coordinating walking gear.

What dogs is the medium harness made for?

The medium size is intended for medium-breed dogs and large-breed puppies. Its adjustable length runs from 20 to 30 inches (50.8 to 76.2 cm), so compare your dog’s fit with that range when choosing this size. The harness is adjustable to accommodate growth during puppyhood, while this specific medium size has a defined length range.

• Size: Medium.
• Width: 3/4 inch (1.9 cm).
• Length: adjustable from 20 to 30 inches (50.8 to 76.2 cm).

What is the harness made from, and how are its seams finished?

The webbing is 100% first-run nylon, custom dyed to help reduce fading and color bleeding. Box stitching secures the ends with heavy-duty thread, and the finished stitching sits away from your dog’s body to help protect the coat from irritation. The harness is designed to provide comfort and control for walks, training, and play, without the discomfort associated with traditional no-pull harnesses.

• Material: first-run nylon webbing.
• Construction: box-stitched ends with heavy-duty thread.
• Finish: stitching placed away from the dog’s body.

Can I coordinate it with a collar and leash?

Yes. Hamilton Classic Nylon collars and leashes are available in coordinating colors for a matching set. The collection includes 4-foot and 6-foot leash options, so you can pair the black harness with compatible color-coordinated walking gear.

• Matching adjustable dog collars are available in the Classic Nylon collection.
• Matching leash lengths include 4 feet and 6 feet.

Hamilton has made pet and large-animal products since 1973, with a focus on nylon webbing, thread, and hardware for pets and animals of different sizes. The medium black harness suits owners of medium-breed dogs or large-breed puppies who need an adjustable option for everyday walks, training, and play. Its 3/4-inch nylon webbing, adjustable 20–30-inch length, and reinforced buckle make it a practical fit for those uses.
