How do you get dog hair off clothes?

Take a 10 inch piece of packing or Duct Tape and join the ends together forming a loop with the sticky side out then "roll' the tape across your fabric until it's so full of hair that it no longer sticks. Throw that hair laden piece of tape away and repeat the process until your garment is hairless! Or you could go to the store and buy a lint roller which uses the same process but it has a handle and is MUCH easier to use.
