we also have 5 dogs, fairly big ones too. a golden, an australian shepherd mix, and 3 lab mixes. we were a brady bunch family, i came in with 3 and dh came in with 2. they mostly get along except for the 2 big males, who rumble at each other CONSTANTLY and occasionally fight for real. but they are pretty evenly matched, so we usually just let them get it out of their systems and go on with our day. we also have 2 cats, who couldn't care less about the dogs and the (seemingly inferior) role they have in the house. they are all our babies though. not sure what will happen when the human babies start to show up, but i guess it will be a learning process!
