The ultimate in vehicle safety harnesses, the Roadie is constructed from parachute-grade nylon webbing and features a figure-8 design to secure your dog without causing neck injury(as a collar might). Three position adjustable strap connects to your cars rear seatbelt and allows you to regulate the dogs freedom of movement. If you purchase one sized for a dog under a year old, All Labs will discount the purchase of a second harness when your dog outgrows the first. The used harnesses are donated to the Humane Society so that other dogs can benefit. Please allow 3 weeks for delivery.
