What is a good tool for getting dog hair off a couch?

Trying to get dog hair off of a couch when they're constantly shedding, can be a daunting task. But, their are a few options to choose from. Keep in mind, depending on what kind of dog you have (long hair or short hair) not all of these methods are going to work for you. You'll have to use trial and error on this one. Luckily, all of these products are fairly inexpensive! The Pet Hair Sponge has received great reviews, though some people seem to think a regular damp sponge would work just as well. The Petmate Pet Hair Magnet is great if you have a large area to cover and do it on a weekly basis. The 3-in-1 Pet Hair Remover works on your pet, and on fabric. The Pledge Fabric Sweeper is new and seems to have some good reviews. The only con is that it is non reusable. Once you fill up the compartment with pet hair, you have to trow it away and buy a new one. Bummer! It's a cool concept. All in all, it's a great time saver!
