4Knines

4Knines is a US-based brand founded in 2013 by dog owners who wanted cargo and seat protection durable enough for large dogs and heavy outdoor use. The company sells direct through its own website and Amazon, and donates a portion of proceeds to dog rescue and service-dog organizations.

The core product line is cargo liners and seat covers for SUVs and trucks. The flagship cargo liner uses K9-Shield®, a proprietary waterproof textile laminate, rather than a rubber or TPE construction — giving the product a fabric feel while maintaining waterproof protection for the cargo floor. All products are manufactured with stitched (not heat-pressed) seams, which the brand cites as the primary durability differentiator vs. lower-cost alternatives.

4Knines products are marketed for pet travel but are used by general SUV owners for grocery protection, outdoor gear hauling, and general cargo area protection. The brand has delivered 15+ product iterations since launch and carries a lifetime warranty.
