We have 3 indoor dogs, a labrador, a miniature Schnauzer, and a mIni poodle. I purchased a total of 5 muddy mats to go in front of all the outside doors, 1 in front of the fridge and a long runner by the kitchen sink. We were installing new flooring, so I waited til the new floors were down to use the muddy mats. I put the 3x5 at the front door, since thats where my 3 dogs go in %26 out. I shook the rugs out %26 vacuumed weekly at the very least. The very first time I washed the large mat, (being sure to follow all washing instructions), it came out of the washer with the ENTIRE rubber backing shredded! I was horrified! This rug was fairly expensive and I thought about it for quite a while before I purchased them. Now I'm afraid to wash my other ones! While these rugs look great, if they are not going to hold up to washing, then I say save your money and don't buy a muddy mat!!
