This dedicated car seat for dogs makes car rides safer by connecting securely to one of your vehicle's seat belts. The included Happy Ride Seat Belt Tether attaches your dog's harness to the seat belt (for optimal safety we recommend using a crash-tested Happy Ride Safety Harness, sold separately). The sturdy, rigid frame is easy to assemble and install in the front or back seat of any car, truck or SUV with seat belts. The strong, lightweight plastic panels lock together with no tools required. The special 9-inch high raised seat platform makes this a dog booster seat too, so even small dogs are able to see out the window and safely feel the breeze. The safety seat supports furry friends up to 30 pounds so they can relax and enjoy sleeping the miles away on the comfy fleece liner and cushion.
