Can Teething Cause Excessive Licking In Dogs?

Mckenzie is right, but I would also add, quite often, puppies will swallow their baby teeth so you may not ever see any laying on the floor or outside on the ground. Swallowing their baby teeth does not hurt them, but be sure to provide your pup with some hard rubber toys to chew on so he can cut in his adult teeth easier. Make sure to have him checked by his first birthday to be certain all of his baby teeth have come out. Some baby teeth will not fall out, and if they stay in the mouth then they can cause premature rotting of his adult teeth.

It may for some dogs.It did not for my dog.but since  they are losing teeth and new ones are growing in it could be because it hearts there mouth.try checking with a vet just to make sure.
