I love my dog but I don't love my dog in my car, because he shed so much! His nails are also really sharp and quite frankly he likely can't fit comfortably in my CLS, as he is huge.
But in my Range Rovers and Toyotas I couldn't get his hair of my car with top of the line vacuums and lint removers. I ended up stumbling across this Pet Hair Remover and can fully endorse it. For ~$8 The Chemical Guys pet hair remover works awesome and is worth it's price.
It clumps the hair so it is easier to remove and pick up. You then pick up the clumped hair and remove the clumped hair off the pet hair remover.
