Width means presence, and the NX3 delivers it at every size. This is a 2.5"–3" wide personalized studded handcrafted Italian leather dog collar built for Cane Corsos, Mastiffs, XL American Bullies, and Presa Canarios — or any dog with the neck and the presence to carry it. Dome studs run the full collar length in a clean, repeating pattern that is bold without being overdone, paired with a custom-engraved nameplate that makes every collar unmistakably specific to your dog.
Choose 2.5" for a substantial, commanding look on large breeds, or go full 3" for maximum visual impact on the biggest dogs in the lineup. Either way, the construction underneath doesn't change. A dense 9–10 oz. Full Grain Bridle Leather base gives the NX3 the structure to hold its shape and stand up to daily wear without softening or stretching out. The Full Grain Italian Leather face goes over that in your choice of color — from classic black and rich cognac to bold croco textures and everything in between.
Unlike bonded leather that cracks inside a year or nylon webbing that frays and retains odor, this collar is built from material that improves with age. You choose the leather color and hardware finish. We cut, layer, stitch, and inspect every collar before it ships — by hand, in the USA, by a veteran-owned shop that has been doing this since 2007.

Since every collar is made to order, we cannot accept returns or exchanges for sizing issues — so please measure before you order. With your dog standing on all fours, wrap a soft tape measure snugly around the neck. Don't go by an old collar or a rough guess — an accurate measurement is the only way to guarantee a perfect fit. Questions? Message us before ordering and we'll make sure you get it right.
We build collars for dogs that deserve the best — working dogs, show dogs, and beloved companions alike. Every piece that leaves our shop is inspected by hand, stitched with care, and designed to last the lifetime of your dog.
