Hamilton Adjustable Nylon Dog Harness, Large Red, 1-Inch Webbing

The Hamilton Adjustable Nylon Dog Harness is made for walks, training, and active play, with a large 1-inch-wide webbing strap that adjusts from 30 to 40 inches (2.54 cm wide; 76.2–101.6 cm long).

• Large size for medium or large breed dogs — adjustable length helps provide a customized fit.
• 100% first-run nylon webbing, custom dyed — helps reduce fading and color bleeding.
• Box-stitched ends sewn with heavy-duty thread — provide a secure hold.
• Reinforced buckle teeth/tines — designed for higher break strength and longer durability.
• Red color — pairs with matching Hamilton collars and leashes in the Classic Nylon collection.

For everyday outings, training sessions, and active play, a harness needs to offer a secure fit while allowing comfortable movement. Hamilton’s adjustable nylon design provides flexibility and control, with finished stitching positioned away from your dog’s body to help protect the coat from irritation.

What construction details support comfort and strength?

The harness uses first-run nylon webbing and reinforced buckle teeth/tines. At the ends, heavy-duty thread secures the box stitching, which is finished away from the dog’s body. This construction is designed to provide a secure hold while reducing contact that can irritate the coat.

• The nylon is custom dyed to help limit fading and bleeding.
• Box stitching is placed at the harness ends.

Can I coordinate it with a collar and leash?

Yes. The red harness coordinates with matching Hamilton dog collars and leashes from the Classic Nylon collection. Matching leashes are available in 4 ft (1.22 m) and 6 ft (1.83 m) lengths, so you can assemble a coordinated set for outdoor activities.

• The collection offers adjustable collars in matching colors.
• The harness is designed for walks, training, and active play.
