Dogs often lick the floor just for the taste and texture. However, if your dog is licking obsessively for long periods, then it might be ELS or excessive licking of surfaces. ELS can be caused by stress, anxiety, or in rare cases OCD. More commonly though, ELS is the result of a gastrointestinal problem.
Why is my dog licking the floor all of a sudden?

Is it normal for dogs to lick the floor?
Remember, licking the floor can be a totally normal behavior, especially if your dog is lapping at the linoleum while you're making dinner or dishing up her kibble—but if the behavior starts suddenly, increases in frequency or intensity, or happens when there is no food around, it could be a sign something is wrong.
