Matching Leather Dog Collar and Harness Set: How to Build One
The short answer
A matching leather collar and harness set works because each piece does a separate job: the collar carries identification all day, the harness takes the lead so pulling force goes through the chest. The Leatherius leather dog harness at about $50 pairs with any collar from the same distressed cowhide line starting at about $36, and both take the same three lines of free engraving.

The one thing that trips people up is measuring. A collar is sized by neck circumference and a harness by chest circumference, so a dog can be a medium in one and a large in the other.

The two size charts side by side
| Size | Collar, neck circumference | Harness, chest circumference | Strap width |
|---|---|---|---|
| S | 10–12 in (1 in wide) | 16–20 in | 5/8 in |
| M | 11–14 in (1 in wide) | 19–25 in | 3/4 in |
| L | 13–17 in (1 in wide) | 25–30 in | 1 in |
| XL | 16–24 in (1 in wide) | 30–39 in | 1 in |
Measure the neck where the collar sits and the chest at the widest point just behind the front legs. Order each piece from its own measurement rather than assuming the sizes line up. Both round up when you land between two. The collar method is spelled out in our dog collar size chart.

What makes a set look like a set
The same hide
Leatherius collars are cut from distressed cowhide, and the leather harness is built from leather in the same workshop, so the two age at a similar rate. A collar bought a year earlier will be a shade darker than a new harness for the first few months, then the two converge as the harness catches up.
The same engraving format
Both pieces take up to three lines of text at no charge. On the wider straps you get 18 characters per line; on the narrower ones, 12. Keeping the same layout on both – name on line one, mobile number on line two – makes the pair read as a deliberate set rather than two separate purchases.
The same hardware feel
Decide once between the click of a fast-release buckle and the belt-style hold of a pin buckle, then apply it across the set. The fast-release leather collar at about $36 is the quick option. The classic belt buckle collar at about $56 is the metal-only one.
Adding the leash
The Leatherius leather dog leash completes the set at about $50. It is 1 inch wide and 40 inches long, built from two leather strips sewn together, with a clasp that opens in one motion and the dog's name added free. Clip it to the harness for walks and let the collar stay on the neck as identification. Our older guide to leather lead and collar sets covers the two-piece version of this decision.
If you want a fabric set instead, the webbing dog harness is about $50 and pairs with the webbing collars in the same patterns. That route makes sense for a dog who swims, for the reasons laid out in leather against nylon.
Why the harness carries the lead
Attach the lead to the collar and every lunge loads the throat. Attach it to the harness and the force goes into the chest and shoulders. For a dog who leans into a walk, that is the whole argument. It is why we suggest running both pieces rather than picking one. The detail is in our guide to the best leather collar for dogs that pull.
For a calm walker, the collar can take the lead on short outings without much thought. The set still earns its place, because a harness distributes weight better on a long hike and gives you a second attachment point in traffic.
Budget for the set
A leather collar at about $36 with a harness at about $50 comes to $86. Add the leash at about $50 and the full set lands at roughly $136, engraving included. Stepping the collar up to the pin buckle version adds about $20. A poop bag holder from the same leather line is about $35 if you want the walk kit finished, and the whole range sits in all dog products. Collars alone are at the dog collar collection and leads at dog leashes.
FAQ
Should a dog wear a collar and a harness at the same time?
Yes, and it is the arrangement we recommend. The collar stays on the neck carrying the name and phone number, while the harness goes on for walks and takes the lead.
Is my dog the same size in a collar and a harness?
Often no. Collars are sized by neck and harnesses by chest, so a dog with a broad chest and a slim neck can be a medium collar and a large harness. Measure both before ordering.
Can I get the same name engraved on both?
Yes. Leatherius engraves up to three lines free on collars and on the leather harness, at 18 characters per line on the wider straps and 12 on the narrower ones.
How much does a full leather walking set cost?
A collar at about $36 with a harness at about $50 comes to $86. Adding the leash at about $50 takes the set to roughly $136, with personalization included on every piece.
