Since cattle and gorillas both see a dog as a primary predator, these animals will unite together to fight against these dogs. When the dogs have all been either killed or chased off, it's questionable whether the two bovines will then turn on the gorilla, or vice versa. It's probable that the two animals will turn on the gorilla, especially if they've never seen one before and believe it too is a threat that needs to be dealt with; it's also probable that the fight that would ensue when all thirteen animals are put together would be VERY confusing, and it would be thus quite difficult to see who would really win.
The reason being is that the gorilla may see both the cattle (the ox and the bovine) AND the dogs as a threat and try to fight all twelve at the same time. If this happens (which is highly likely), then it's likely that the gorilla will be the first to go from getting serious injuries from both the ox and bull's (assuming the bovine is indeed a bull) horns and the dogs it is trying to fight off. So that leaves the dogs with the two animals. It's likely, during such a confusing fight, that the pack may have lost several of its members already, and only have a handful left to fight these two cattle. And that battle would be short-lived, as the bull and the ox would have no problems dealing with what's left of the pack of dogs.
So, in that scenario above, the ox and the bull (being the bovine) will win.
The gorilla will defeat the cattle-beast easily because the gorilla is more suited when it can stand and grab things.
The crocodile could win, but would get badly injured by the ox and the cattlebeast's body.
There are just too many variables to this question to be able to answer, simply because there are more animals involved than can be justified in a normal "who-would-win" question.
Most likely the gorillas.
Some dogs will get the cattlebeast by distracting it and others will go behind to bite out the hamstrings. If the dogs avoided the horns and the hooves, the dogs will get the cattlebeast at the end.
Probably the gorilla, as cougars do not like to fight an animal that will stand up to it and be prepared to fight it.
a silver back gorilla would win easily win!
Gorilla vs Elephant? The Elephant no contest
Probably the gorilla, unless the small man was armed with a gun.
A rhino could flip a gorilla
A gorilla has no chance to fight a rhino.
The gorilla can win because of his mobility but likely the elephant unless the gorilla is smarter then the average gorilla. The elephant just needs a few pounces or 1 charge to win but the gorilla needs to be quick and persistent which is harder to do in a fight so my moneys on the elephant.
