When the dogs aren't in their crates I take the mats outside and give them a good shake. Each dog has 2 mats. I alternate because they are great shedders. The mats are identical but 2 different sizes (specific for each crate). I try to remove as much hair as possible before putting into the washer and dryer. Wish I had a clothesline because I would use it instead of my dryer. Our mats are heavier because we use old bath towels.
