I need advice on Puppy Love: I don't want to be a heart breaker

This week I have been observing Barnabus.  The most puppy of them all.  He is funny, goofy, and has a lot of energy which are all very entertaining, but he also occasionally comes in for the kiss. I think he has a crush on me, and I am not always sure what to do.  I like Barnabus, but I am afraid he more than likes me, he loves me.  I think it is what they call puppy love.  I want to be his friend, but when he gets too close, little growls come out of my mouth.  I promise it slips out and I can't help it.   Then he has to run to tell his Master that I was being mean.  I don't mean to hurt his feelings, but I just don't feel the same way.   I really am a good little dog.  I know, because my mom tells me all the time.  I used to have puppy love feelings towards Charlie, but they too passed.  Now, I just have love for my mom, but it is a different kind of love.  Someday, he will grow up and meet someone special.  Until then, I need advice on how to get through these next few days.  Do I tell him?  Do I move on to the next room when he is around?  HELP!!!

Yours truly,
