Anyone who has ever owned a shedding dog or looking at how to remove dog hair from carpet knows how difficult it can be to keep the house free of pet hair. Vacuuming regularly helps, but it seems like the minute you finish, your dog starts shedding again. One way to remove dog hair from carpet and upholstery is to use a lint roller.nnLint rollers are designed to pick up small particles of dust and hair, and they work just as well on dog hair as they do on lint or dust. To use a lint roller on your dog, simply roll it over your pet's fur in the direction of the hair growth. The sticky surface of the roller will grab any loose hairs, making them easy to remove. For best results, use a fresh sheet of adhesive for each stroke.
