Yeah, I guess we did. No, that would have been a nightmare if we could never have our dogs together.
At first when they got into a fight I would crate one or both of them immediately. But I switched to making them stay close to each other and letting them sniff each other after a fight. I think it worked to show them that neither one actually meant harm. I did this recently, in fact. Dorie ran into Luna while chasing a ball which made Luna growl which made Dorie snap back. I told them to stop (not before getting bitten myself

) and let them sniff each others' noses and that was it and both went back to playing.
