Ha! Yes, I have had Bs that do this….particularly one named Bubba Roi, who doesn't live with us anymore...but he would lick our pants! It was really a creepy feeling, and we tried to ignore it, but he definitely enjoyed doing it. Now anytime one of our dogs licks clothes we say 'knock it off Bubba'
I don't know why they do it...I think it is affection, but maybe they don't like the way we actually taste!
