My dog has started a new habit that is driving me crazy. A couple of weeks ago Cody (13 months old) started licking the floor. He just walks around the house and licks the floor constantly as he walks. He licks the carpet, the tile, the concrete in the basement, anything. He just licks as he walks. We have cleaned and vacuumed repeatedly and it doesn't help. Any ideas? Anyone else's dog so this? This can't be good
