I have another dog, a 3 yr old Rat Terrier, Sadie, and she only licks to give kisses and you have to ask her for those, whereas Maggie, the little one licks constantly, all the time. Sadie is much calmer than Maggie, but always has been. Thanks everyone for posting their stories. Sadie is the alpha so maybe she doesn't feel she needs to lick anyone. Maggie is more submissive around us too.
