I don't think there are any animals -except humans- who'll actually attack a wolf pack in the first place, unless that animal be rabid.
And even then, a whole wolf pack can take down a grizzly bear even, and since bears are normally solitary creatures, I doubt a bear would stand a chance.
However, moose, -and other hooved animals- although they are prey, their kicks can kill a wolf, and if a heard happens to stampeded where the wolves are, they just might kill off the pack.
Yeah, I don't think any animal, except a human, can kill a pack of wolves, and I highly doubt any animal would bother attacking wolves in the first place.
If a pack of wolves can kill a grizzly then it can kill a polar bear!!!
A pack of wolves definitely because werewlves can kill vampires so why not one hippo.
Yes, in most cases. They will kill the whole rival pack if they can. They will also kill deomestic dogs if they come near.
Oh, yes, indeed!
A pack of wolves and even a grizzly.
The collective nouns are a pack of wolves or a rout (or route) of wolves.
A pack of wolves.
A pack of wolves is a collection of wolves.
The question depends on the quantity and strength of the wolves, and the strength and health of the bull moose. Usually, a pack of wolves (5 or more wolves) would attack and kill a young moose or an injured moose that is too weak to fight any longer. Wolves always look for weak animals for them to kill, like an injured moose. Even if the wolves attack a healthy, strong moose, the wolves would win but they would get some members injured. Bull moose can sometimes drive off a pack of wolves if they are large and the wolves were not eager to fight down it. But bull moose can also kill or fend off a pack of wolves if they were strong and healthy enough to do so. Bull moose are pretty aggressive and powerful enough to kill grizzly bears or brown bears, which makes them quite dangerous enough to fight off a pack of wolves. Ten or eleven strong wolves are enough to bring down a healthy, strong rutting bull moose if they avoid the moose's hooves/antlers, and gave painful bites to the hamstrings.
Maybe... but a pack of wolves usually can rob a tiger of his/her kill. A tiger most of the time will avoid direct conflict with a pack of wolves, because any injury will great hamper its survival due to his/her lonely life in the harsh environment.
A very large pack of wolves could kill a single Grizzly bear
to feed more pack members for longer.
