Hamilton Adjustable Nylon Dog Harness - Lime Green, Extra Small for Puppies and Small Dogs

The Hamilton Adjustable Nylon Dog Harness in Lime Green (Extra Small) is a lightweight, 3/8-inch wide harness designed for puppies and small breed dogs, with a fully adjustable fit from 10 to 16 inches. Made from first-run nylon with box-stitched ends to reduce chafing, it prioritizes comfort and control on daily walks. This harness is part of Hamilton's Classic Nylon collection, available since 2004, and can be paired with matching collars and leashes for a coordinated set.

Finding the right fit

This Extra Small harness is sized for dogs with a chest girth between 10 and 16 inches. The strap is 3/8 inch wide, narrow enough for small dogs but strong enough for daily use. It weighs just 0.99 ounces, so it won't burden a tiny pup. The harness is fully adjustable on both the neck and chest straps, allowing you to customize the fit as your puppy grows or for different breeds.

Built for everyday use

Hamilton uses 100% first-run nylon webbing that is custom dyed to reduce fading and color bleeding. The buckle features reinforced teeth and tines for higher break strength and longer durability. Each end is box stitched with heavy-duty thread, and the stitching is finished away from the dog's body to keep the coat free from irritation. These construction details make the harness reliable for daily walks, training sessions, and active play.

Matching accessories

If you want a complete set, Hamilton offers adjustable collars and 4-foot or 6-foot leashes in the same lime green and other Classic Nylon colors. Mix and match or keep it uniform—the harness is compatible with any standard leash. Using the matching leash ensures a consistent look and feel.
