Every detail of the Vanguard Set replaces pet-store shortcuts with solid metal hardware and double-layered stitched hide.
Replaces brittle plastic side-release clips with a heavy-duty silver metal pin buckle, riveted keeper loop, and 4.5mm welded D-ring that will never snap mid-lunge.
A clean single row of blunted 8mm silver conical studs shields your dog's neck from off-leash bites, backed inside by flat, smooth flush-set rivets that never rub skin.
Comes with a 48-inch round-stitched black rolled-leather lead and 360° silver swivel snap hook ($45 value) that sits smoothly in your palm with zero rope burn.
Twin rows of heavy-gauge black perimeter lock-stitching bind two layers of sealed matte leather that soften like a favorite pair of boots without stretching or stinking.
Cheap spiked collars leave rough screw threads exposed against your dog's throat. We compression-rivet every polished silver conical stud with a flat, mirror-smooth interior silver cap set flush into the inner leather lining—so it glides gently over fur even on 24/7 indoor wear.
When a 70-pound dog bolts after a squirrel, plastic prongs shear off. Our solid silver-tone belt buckle threads through five laser-spaced sizing holes along a 4.0mm double-layered leather strap reinforced with continuous perimeter lock-stitching and flat silver keeper rivets.
Flat nylon leashes saw into your knuckles when your dog pulls. Our included 10mm round-stitched rolled-leather leash distributes tension evenly across your palm and clips to the collar via a dual-riveted 360° silver swivel snap hook that prevents tangles.

Why We Built the Vanguard Set: We got tired of choosing between $20 big-box nylon collars whose plastic clips snap at the worst possible moment and $140 boutique leather setups that charge extra for the leash. The Cosari Vanguard pairs a 4.0mm double-layered matte black stitched leather collar with a matching 48-inch stitched rolled-leather leash in one box. It gives protective dog owners tank-like metal hardware, functional neck protection, and rope-burn-free walking comfort.
Materials & Hardware Craftsmanship: Crafted from sealed, full-grain matte black leather with heavy-gauge black perimeter lock-stitching. The collar features a single centered row of 8mm blunted solid silver conical studs backed by smooth, flush-set interior rivets, two flat silver keeper rivets, a solid silver pin buckle, and a 4.5mm welded D-ring. The included 48-inch × 10mm rolled-leather leash is length-stitched for zero stretch and reinforced with dual silver compression rivets and a 360° swivel trigger snap hook.
Foolproof 2-Finger Sizing Guide: Measure around the middle of your dog's neck with two flat fingers slipped underneath the tape for comfortable breathing room. Small fits 11"–14" necks; Medium fits 14"–18" necks; Large fits 18"–22" necks; X-Large fits 21"–25" necks. Each collar features 5 precision-punched adjustment holes spaced 1 inch apart so you can fine-tune the fit as your dog grows or sheds their winter coat.
Free 5–7 Day US Shipping: Every order ships free with full tracking and delivers in 5 to 7 business days.
30-Day Trial: Try it at home for 30 days risk-free. Need help? Email us anytime at support@buycosari.com.
2-Year Warranty: If anything goes wrong within 2 years, we replace it free of charge or refund your order in full.
The heavy-duty silver swivel snap hook rotates a full 360 degrees as your dog circles on walks, keeping the round rolled-leather leash completely untwisted in your hand.
Rain, snow, and mud wipe clean in seconds with a damp cloth. Unlike foam-padded or nylon collars, solid stitched leather won't trap mildew or wet-dog stink.
If a single silver stud, rivet, buckle pin, swivel clasp, or perimeter stitch ever fails within 24 months of daily walks, we send you a brand-new set free.

Press the thumb lever on the heavy-duty silver swivel snap hook of your included rolled-leather leash and lock it onto the collar's welded silver D-ring.
Slip the supple stitched leather handle over your wrist and enjoy total pull control, zero palm friction, and classic saddlery confidence on every walk.
This arrived sooner than I expected, which was a nice surprise! My Staffy destroys plastic buckles, so I really appreciate the solid silver belt-style buckle and riveted leather strap. The collar looks and feels premium.
The matte black leather, silver spikes, and matching rolled leash look great together. The collar has a nice substantial weight, adjusts easily, and I prefer the metal closure to plastic. Our dog didn't try to take it off, so everyone in the family is happy.
The small fits my 11.5-pound poodle really well. I worried the hardware might be too heavy, but she's worn it for a couple of months without any bother. The silver pin buckle is easy to use, and the flat interior rivets don't poke her neck.
I've had leather collars on my two dogs over the years, and this leather reminds me of a good broke-in boot. After months of daily walks, the thick stitched collars and rolled leashes are softening up without fraying like nylon can.
I've had plastic clips fail at bad times, including on walks around other dogs, so I appreciate the silver belt buckle and D-ring here. The rolled leash has a heavy swivel snap hook, too. The smooth matte black leather feels soft and well made.
I was pleasantly surprised by how well made this is. The thick double-layered stitched leather feels tough but still supple. The solid metal buckle, riveted D-ring, and swivel leash clasp give me confidence that the hardware won't break.
my dog spends a lot of time outside, so i pay attention to how collars handle wet weather. the matte black leather has held up nicely, and the silver-tone spikes, rivets and buckle still clean up well after rainy days.
This set is absolutely beautiful. The heavy-duty buckle, D-ring, and leash clasp all feel solid, and the black stitching around the collar is nicely reinforced. I love the silver conical spikes against the matte black leather and the matching rolled leash.
The single row of polished silver spikes gives the matte black leather some visual interest and a bit of a luxurious look. The matching rolled leash ties it together. I'd recommend the set to anyone looking for a quality collar with some personality.
The black rolled-leather leash feels comfortable in my hand, even when my dog pulls. I like the round stitched cord, and the silver swivel snap hook and two silver rivets at the attachment end feel solid. I'm not worried about the hook breaking.

Yes. Every Cosari Vanguard order includes both the Matte-Black Spiked Leather Collar and the matching 48-inch (120cm) Black Stitched Rolled-Leather Leash with a heavy-duty 360° silver swivel snap hook in the box—no separate add-on required.
Completely smooth. Every polished silver conical stud is compression-set with a flat, flush-capped interior silver rivet backed by double-layered stitched leather. There are zero sharp threads, burrs, or rough edges touching your dog's fur or skin.
No. The 8mm solid silver conical studs feature rounded, blunted tips. They are engineered to stop an aggressive off-leash dog from clamping down on your dog's neck while remaining completely safe for your hands and friendly play.
No. The 4.0mm hide is finished with a sealed, colorfast matte topcoat that sheds rain and snow without transferring black dye onto white or cream coats. Unlike spongy nylon or foam-padded collars, solid stitched leather does not trap stagnant water.
Wrap a soft tape measure (or a piece of string you measure with a ruler) around the center of your dog's neck where their collar naturally rests, sliding two flat fingers underneath the tape for comfortable breathing room. Match that measurement to the center hole of our size chart.
You are covered by our 30-Day Walk & Break-In Money-Back Guarantee plus our 2-Year Hardware & Stitch Warranty. Try the collar and leash on real walks for 30 days—if you need a size swap or aren't thrilled with the build quality, we will exchange it or refund 100% of your purchase.
