Hmm I have never heard of that, Is she only licking not biting?
My older dog Jess LOVES to lick my dads head for some reason LOL He has a shaved head and maybe it just feels nice on her tounge?
Im not sure but this could be what your dog is doing also if it is only licking.
You can get a spray from the pet store that tastes kinda bitter to stop them from biting furniture which you could try, but if she licks the walls too then you would pretty much have to spray the whole house LOL.
Aslong as she isnt biting I dont see the harm in it but you could ask your vet next time your there.
