Dogs licking the floor?

I have a question...My 2 year old Doxie likes to lick our linoleum floor...all the time! I don't know what he likes about it, or why he does it. And I don't know if it's harming him or not. Do you have any suggestions to make him stop?

I doubt it's harming him lol. Maybe there's something that's been spilt on it? Maybe he likes the cold feel? Maybe he's just saying "Hey mom, you don't gotta mop, ya got me!"

My dog, Nebo, licks EVERYTHING....the floor, the oven, the dishwasher, the toilet, the bathtub....I think he has a thing for cold smooth surfaces too.

I wouldn't let him lick it if it's recently been cleaned!

My dogs have licked the floor before, it was because there was some sort of food that had bee dropped there and yet they still smelled it.

Kito licks the floor--but the carpet, not the tile--weirdo:D
He and Abbey also lick the bed, the pillows, the couch, you name it, their tongues are all over it!!!
