Thule Dog Mat, Cappy and Leash Hooks: Car Kit Explained

A practical guide to three Thule dog car accessories: the Dog Mat for crate grip, the Cappy crash-tested harness, and Leash Hooks for organization. Learn which pieces fit your travel setup.
Quick answer
Start with the Thule Cappy if your dog rides on a seatbelt, add the Thule Dog Mat if you use a dog crate, and choose Thule Leash Hooks only when you already own a Thule Allax crate. Buy all three only if you switch between crate and backseat travel.
Crate grip versus seatbelt security
The Dog Mat and Leash Hooks are crate accessories, while the Cappy is a harness that secures your dog with the car's seatbelt system. That difference decides your first purchase. If your dog travels loose in the backseat, the Cappy is the safety item. If your dog already rides in a crate, the Dog Mat improves footing and the Leash Hooks keep gear tidy.
The catalog does not list a crash-test rating for the Dog Mat or Leash Hooks, so treat them as comfort and organization add-ons, not restraints. The Cappy is described as crash-tested, but the supplied facts do not include a specific test speed or standard. Check the product page for the full harness specification before relying on it for a particular vehicle.
When a cutting-pattern mat is worth it
The Thule Dog Mat is pre-made with cutting patterns, so you trim it to fit your crate rather than accepting a loose universal mat. That matters because a mat that bunches at the door can make jumping in and out less stable. The trade-off is that trimming is permanent: measure your crate floor before cutting, and accept that the mat will not transfer cleanly to a different crate size later.
Leash Hooks only make sense with an Allax crate
Thule Leash Hooks attach to the sides of a Thule Allax dog crate. If you use another crate brand or no crate at all, these hooks have no mounting point and are not a useful purchase. They come in a pack of two, which lets you separate leash and collar storage, but they do not add safety or restraint.
Decision rules for building your Thule dog car kit
- If your dog rides on a seatbelt: Choose the Thule Cappy in the correct size and route the seatbelt through the harness as directed. Do not add the Dog Mat or Leash Hooks to this setup unless you also use a crate. Confirm harness size against your dog's measurements before ordering.
- If your dog rides in a crate: Start with the Thule Dog Mat and trim it using the pre-made cutting patterns to match your crate floor. Add Leash Hooks only if the crate is a Thule Allax. Measure the crate floor before trimming; cuts are permanent.
- If you switch between crate and backseat: Buy the Cappy for seatbelt rides and the Dog Mat for crate rides. Keep the Leash Hooks on the Allax crate so leash and collar stay with the crate between trips. Two restraint setups cost more than one; decide whether you need both before buying all three.
- If you own a non-Thule crate: Skip the Leash Hooks because they are made for the sides of a Thule Allax crate. The Dog Mat may still work if you can trim it to your crate floor. Check mounting compatibility before adding crate-specific accessories.
Product facts at a glance
- Thule Dog Mat: Non-slip silicone mat with pre-made cutting patterns for a custom crate fit. Gives your dog a stable surface when jumping in and out, provided you trim it to your crate floor.
Thule Dog Mat - Thule Cappy: Crash-tested dog car harness that secures your dog with the car's seatbelt system. A restraint option for backseat travel rather than a crate add-on, so it suits a different travel setup.
Thule Cappy - Thule Leash Hooks: Pack of two leash hooks designed to attach to the sides of a Thule Allax dog crate. Keeps leash and collar organized only if you already use a compatible Allax crate.

- Travelers who want to organize leash and collar on the crate sides
Not for
- Owners with a non-Thule crate who need mounting accessories
- Dogs that ride loose in the car without a crate or harness
- Anyone expecting the Dog Mat or Leash Hooks to restrain a dog in a crash
