Dog licks slate floor, Why?
 

Need prognostication on the following:

Dog licks floor in kitchen

Associated facts:
- Floor believed to clean
- Floor made of slate
- Dog not emotionally well in general
:)

My professional diagnosis: Weird dog. ;)

What do you mean by the dog is not emotionally well in general?

I know that slate is the top layer of rock that a quarry removes so they can begin to mine to "good" rock, so I am not sure if maybe it has a high salt content, and maybe your dog is licking for that?

my kitchen floor is human clean too but what a dog smells is so strong and he may be just getting the last of a good meal, my girl licks the linolium in the kitchen even after i have scrubbed it clean. dogs are just weird. and what is an emotionally unwell dog?? I knew of a woman up north that would do hypno therapy on dogs and tell you of their worries and past life experiences, did some one like that diagnose your emotionally unwell dog??;)

Maybe likes the coolness of the floor or what you are cleaning it with.
