Gonzo and Fozzie are two TOTALLY different dogs, and I feel lucky for that. They know they have their own outings, and both of them seem content with the arrangement. When ever I leave one behind, he gets a stuffed Kong, or a really good RMB, or a bully stick, so neither of them pay attention when I'm leaving. I think it's a GOOD thing to take each dog on outings individually, I like the one-on-one bonding time.
Fozzie is very social with other dogs, so he gets to go to the dog park several days a week.
Gonzo is very obedient, and very frisbee/ball-driven, so he gets to go to the park and the lake to play off-leash, usually every day.
Both of them are good with people and behaving in public, so they both come to pet stores, walks, Agility/Flyball classes, tournaments, dog fairs, etc. : D
