depends... on size of wolf, type of wolf
tiger
It really depends on how strong/large the wolves are and how strong/large the lion is.Another AnswerThe lion would win the fight with the two wolves because it has the strength of killing a siberian tiger, while two wolves would have difficulties with. Two wolves are not strong enough to kill a lion, but four or more wolves would totally kill a lion. Even if the two wolves are strong and large, the lion would still kill them, but it could get injured.
10 wolves would win, no question.
wolves
Depending on the size and strength of the black bear and the each of the two wolves, they are both capable of killing each other. A black bear has the strength of killing the two wolves with its size and claws advantage over the two wolves. Black bears have bad aggressions over killing, which would make them more dangerous for the two wolves to kill. But two wolves are strong and dangerous enough to bite the black bear and leave serious pain on it. Most likely, the black bear would win, but it would get injured.

if it were a gray wolf then maybe the wolf would win.
The wolves would win easily but they may not be able to catch the greyhounds.
A cow moose on the rut, especially one that is defending the young from an enemy, is quite dangerous and powerful enough to injure a pack of wolves. Two wolves are good at killing animals that are bigger than themselves, but the cow moose has those hooves and a strong head that could kill the two wolves. The hooves would stomp or trample the two wolves to death if the two wolves do not escape fast. Even if one wolf can distract the moose on the front, and the other can go on the back to rip out the hamstrings, a cow moose would charge at them and knock them to death. In the fight, the cow moose would win.
pack of wolves
The timber wolves.
Pack of Timber Wolves will surely win the fight
