Beautiful animal, although I'm not sure if humans should be swapping spit with any animal...let alone a wild one.
I never see my dog licking his butt, although on occassion he'll lick in the area of his 'junk'.

There was a segment on Dr. Oz or some damn show about letting dogs lick lips of both adults and
