My Jessie has to give me 'kisses' every night before we all lay down to sleep. OK - the bed is crowded - Me - two cocker spaniels and my Sig. Other.....I even bought a bigger bed because I rolled over one morning and landed on the largest part of my anatomy - and Jessie was the only one who jumped down - gave kisses and made sure that I was alright! He doesn't kiss Jeff much - just me. So - I don't know why Bailey 'grooms' you every morning....but I bet it does have something to do with taking care of you - Animals groom to show affection.....so you know you are well loved!
