When you have a breed that learns as fast as an Aussie, no telling what will happen after he dispatches the first rooster who attacked him.No the rooster will protect he will attack the hawk as I have seen to protect his girl in the end taking the beating and giving his life to save hers as for dogs mine know not to run the girls yes he put the dogs in place also
All it took was the second threat from a black cat; if he catches a black cat, it's dead.
Color does matter to him, so not all cats are in peril around him.
