I haven't really had what I'd call a fight, yet. Although Dudley is constantly trying to mount Finn, so, I know it may be just a matter of time before there's a real altercation. As of right now, it's just Dudley being retarded and barking, Freckles barking, and, Finn running laps around the living room, bumping the two small ones around with his big butt. He isn't usually affected by it, but, I did have to nip it in the bud the other night. Dudley got too fresh or something, and, Finn's entire body changed and he wasn't playing anymore. I just raised my voice, but, lowered the tone, and, that was that. I don't know what I'd do if they actually started fighting. Whatever I could, I guess. :/ I'm glad you were able to stop it before it went too far. Toys cause aggression at my house, too. I don't leave any out at all, but, they have griped at eachother over sticks, too, and, that's kindof unavoidable.
