So, we tried to take Flynn camping for the first time tonight. He is currently in a state of high agitation. He is running around in the tent, attacking all the sleeping bags, barking with hackles up at every noise, and generally acting crazy like he does when he is exhausted and overstimulated. I'm sure the rest of the campsite hates us. Any suggestions for calming him down? He won't even sit for more than a second.
