i completely understand LOL ... my bentley is the same way....he just licks, licks, licks...he is also very friendly and happy and just LOVES life...and he shows it by licking!
it gets so bad that i have to clamp my mouth together otherwise he jabs his tongue into my mouth...i love him sooo much but that grosses me out!
he will lick anything - arms, hands, faces, shirts, pants...i think he has an oral fixation or something hehe
i hope someone has a suggestion or tells us this is normal
