A man saved a she wolf from a trap, a few years later she saved his life

This story happened in the far North. A man was going through a forest and he came across a huge, wolf. The man was frightened to death and he could not see at once that the wolf fell into a trap. The beast looked exhausted. It was clear that pretty much time had passed after the wolf fell into a trap. The man came closer and examined the animal. He paid attention to the swollen nipples, in which there was milk. It became clear that there was a shewolf in front of him. There must be hungry pups somewhere n
