Dog licking its lips

There are many times that I see dogs in my vet clinic that are constantly licking their lips, the floor or even the air. This is usually indicative that there is something wrong going on in their mouth or they are nauseated. 

What is lip licking in dogs?

Many dogs will lick their lips for no reason. Lip licking is when your dog is licking their lips just like they do after they have finished eating but they continue to do this sometimes for hours.  

This can be because they are bored, have mouth issues, or feel nauseous. Your dog does not have the ability to put their paws in their mouth and move things around like we can so if there is a piece of food that is stuck they may also excessively lick their lips.
