Why are dogs so loyal?
Some people would say dog are loyal just because they depend on us for food and shelter, so they have to be nice to us. But when you see how dogs react when their humans and canine friends come back after they've been gone for a long time or when they don't come back at all, you know it's about more than food.
Dogs are pack animals. They want to belong to a pack, whether it's made up of dogs or humans, or pretty much any animal. You can look at these Unlikely Animal Friends videos to see all the different kinds of friends that dogs will make. Dogs aren't loners. When they lose a member of a pack, even temporarily, they feel that a part of them is missing.
