My butcher's friend lost his hounds to a wolf pack in idaho a couple of years ago. He tried to get there in time,but the wolf pack killed his dogs. :'(They where trained not to fight each other so they didnt fight back. They were good dogs. So Bill gave his friend the two dogs he had,because he didn't hound hunt anymore. Bill's dog are good Cat and Bear dogs. Well good luck and be safe out there. Shoot a wolf and Cat and post the pic's 
It wouldn't make a bit of difference if they did fight back. In fact I bet they did. Them not fighting each other has no effect on whether they would fight a yote or a wolf. Trust me, I've seen enough photos of hounds torn in half and killed by a pack of wolves to know, it's no contest what so ever.
