I have two big dogs. While I won't let them even near my car (keep a second car to cart them around) I do have faux suede couches that will grab the hair as well.
This is by far the best solution I have found for pet hair removal. Far better than vacuums, sticky stuff and other brushes.
It has little plastic teeth (Similar to Velcro but smaller) that will grab the hair and hold it. You simply use it like a brush. It is good to bring the nap back of the fabric as well.
