When we look at the act of sharing, we see that it involves a capacity to use a resource at the same time as allowing others to make use of the same resource. It also involves the understanding parameters or limitations, that is, the skill of co-existing peacefully while jointly making use of surroundings and resources with others.
When animals travel in packs they are not actually sharing consciously the way that humans would. When they are in packs they are actually protecting each other while assuring that the pack, as a whole, will work together so that all will find food. If you think about it, when the predators go in packs in search of food, they play many different roles. One makes sounds to ward off from their own predators while others search the area and, when it is time to get the prey, a pack can kill and eat it best if they all work together to get a really big prey.
In general, anything that guarantees an animal its safety and its nourishment will make it behave in a docile and even cooperative manner. Even when the animal is so self-sufficient that it does not need to operate within a pack, it can still share with another animal so long as the latter does not take away anything.
Therefore, sharing is a unique behavior that should occur altruistically, if it is to be done properly. Animals cannot think altruistically but they can certainly plan ahead for their own offspring, for the weather, and for the good of a bigger group of their own species. That is what their particular kind of sharing really entails.
