● UNMATCHED PERFORMANCE! Our seat belts are heavy duty, durable nylon which means they aren't easily chewed up or broken down. This means you'll have them for years of car rides to come! ● UNIQUE! With 2 different colors (black and teal) in the pack you can adjust the length for each dog, allowing you to quickly get them in and out of the car. Or, if you only have one pooch, you'll know which seat belt goes in which car. Now that's easy and safe traveling! ● PRACTICAL! Because the seat belts are adjustable length (~23-33 inches) there is no need to buy a specific size. They also stay where you set, so you can find the perfect length once and forget it! Our seat belts are compatible with any dog harness with at least a 0.19" clasp opening. **For your dog's safety ALWAYS attach to a harness, NEVER a collar** The universal seat belt fitting is compatible with most vehicles (0.83" width). Please measure all lengths before purchasing. ● EFFECTIVE! If you've been looking for a way to travel stress-free with your pup, then your search is over! With our swivel latch your dog can move freely and sit comfortable, while staying in the backseat! This keeps them and therefore the driver and rider calm! ● FUNCTIONAL! Tested with our 2 namesake dogs, these seat belts are tangle free so you won't need to stop and adjust, which makes for quicker travel!
