I don’t know where to start when it comes to this product.. let me start by saying; if you plan to get a puppy, have a puppy or any four legged family member this mud-rug is a must. We just added a two month old Dachshund named Lilly to the family, and as you know they don’t arrive potty trained. Well, long story short, Lilly has had many untimely and messy accidents inside, but unfortunately for us they all happened 100% on the mud-rug. I’m not sure what it is about these rugs, but dogs are drawn to them as if they were wee wee pads. We bought three of them because our thought was, if we have more than one, we will have one to put in its place while the soiled one is washing & drying, and it’s worked out perfectly. Once they soil number two on the mud-rug, you just remove the pile with a paper towel or pet disposal bag, and if it’s a messy kind all you do is swap it out with a clean one and throw the soiled one in the washer. It’s that easy! And as far as number one goes, you can rest easy knowing that the super absorbent materials soak up to 30-times their weight with absolutely no lingering odors, but that is completely your call. The main thing is; from day one of laying the mud-rug down, Lilly has NEVER did any business off the of the mud-rugs. They are also a fantastic tool for any type of messes i.e. heavy foot traffic all seasons, messy little ones, etc.. we even keep one in our garage entrance way to keep all the outside elements from entering the house. I can’t say enough about these house saving rugs.
