Yup, you had best be quick or they will turn and nail you. UP- FLIP- KEEP MOVING as needed. Better have grabbed the aggressor though or the other dog will no doubt continue the attack on the dog you are holding. Might need some quick leg/kicking action as well. Dog fights stink!That seems to be the best method. Also from what I've read when you have them by the back legs, keep them moving in a circle so they can't manage to spin around.
