Why Is My Dog Licking Floors In Corners. All dogs use their tongues to lick, that’s what they are made for. So, why does my dog lick the floor?

I have a 12 month year old labrador birch. Possible reasons why your dog licks the floor are that there is food stuck there, it likes the taste, hunger, thirst, compulsive behavior, illness, anxiety or inadvertently rewarding the behavior. A few reasons why your dog might be bored include lack of physical or mental stimulation.
