I previously posted a 2 star on this, I couldn't find a way to edit the original so doing another one.  I originally bought one for back door for dogs, color was ugly and other choices wasn't much better.  I put the black and white rug down in my long hair dogs bed for them to sleep on, they shed like crazy but after a week I didn't notice any hair laying on top of it.  I started running my hand over the rug and the amount of hair it was hiding inside the fibers could have made a sweater.  I'm impressed with its ability to hide dog hair and how easy it is to extract.  I bought a different color to put at the back door where the dogs come in, again, not a pretty rug but it really does a great job on mud and water when they come in.  I recommend them highly, about to buy a 3rd one now.
