Which material is good for floring?

i think marbal is best...

to me actually i think that linoleum is good, why? is because you can easily clean the mess and disinfect the area real good. because you dont have to worry about anything soaking in a hard wood floor. but you might be able to put a training pad over a bigger peace of plastic just say 6 inches each side wider then the pad. so that if the pet misses the pad hopefully he or she hit the plastic. when i went away from home i put my puppy in a doggy kennal with enough space for his comfort with pads laying in it thats the way incase of an accident its was in one small area instead of all around in one room of the floor.
