The dog and baby have been checking each other out for some time now. Even more than that, Rigby will give Claire some friendly licks and she happily watches his antics. They are getting along nicely.
Here is one interaction that I spied the other day. I generally think it's tacky to narrate pets' and babies' unspoken thoughts. I'm going to do it anyway, and I promise I won't do it again:
C - Hi dog, are you going to eat me today?
R - Perhaps, you have fattened up nicely and you taste better each day.
C - True. I'm delicious.
R - Maybe we can work something else out... Shake on it?
C - Deal. Let's keep this our little secret. Act cool.
R - Sigh.
