Awww, you're not a dork! We're not good at leaving our pups either. Shoot, last night our pups all rode in the car when we went out for dinner. Granted, the weather was comfortable, it was close to home and we weren't inside the restaurant long, but they could've stayed home right? Uhhh nope, they gave us those sad eyes and begged to go along for the ride, sigh, so they came. We're such big ol' mushballs.
I know that Harley will have a great time playing with the other pups & all the toys. I hope that you have a wonderful trip.
