Two dogs and at least 1500 feet of carpet, most of white and no problems. There have been a few accidents because they were adult strays, but enzyme cleaners took care of it. Now Lily and Moira can go 14 hours or so in an emergency. Lily has gone longer in stormy weather by her choice. The smaller dog is Border Collie/Lab, so she sheds long silky hair like a Lab. I do have to vacuum often, but it isn't any harder than sweeping. As far as mud goes, they know how to wipe their feet. If anything does get on the carpet, I let it dry and vacuum it up. I do like the white for ease in cleaning without worrying about fading. There is no dog odor on my carpet - a little on their beds, but I wash the beds weekly to keep ahead of it.
Will your sewing machine be in this room? I'd rather have no carpet in my sewing room, but what is, is.
