This allows for the car best suited to a small small dog (eg Yorkshire, Shih Tzu, Chihuahua, Poodle, etc ...) The quality of the strap is pretty average (it is very thin thickness level). For the price, so do not expect a phenomenal thing. But if you have a dog featherweight, this should suffice for protection.
I, who have a labrador 38 kilos, if you have a beefy dog like mine, forget this direct purchase, it is not even worth it! Finally, I am disappointed with this purchase, I will immediately try to resell it. I say "try"!
