They've got a mix for Dachsies too? I looked but never found anything like that. No place around here carries RC, so we always order their food from PetFoodDirect.com. You can get Science Diet from our vet's office, but that's as good as it gets.
I'll give the adult mix some consideration. They share both food dishes (they go back and forth during a meal!) so I didn't want it to be something that one of them couldn't have.
