Night Rituals

Last night he was barking! He's barked before so why is that good? He was outside, at night by himself and barking at something, who knows what, along the fence line which he hasn't done in months. And when I let him and the girls (Olivia and Kobie) out before bed, they raced to the door making loud whiny (hard to explain but fun noises) to go out which, again, is something they haven't done in months!!
