Which animals change their fur color for the winter and which do not?

Does not change color, for example, a wolf. But hares, for example, change their color. In summer, these animals have a gray coat, but in winter they change it to a white coat, so it is easier for them to hide from predators, because they can easily merge with the snow. They also change their fur coat and Arctic foxes. In the warm season, their fur coat is dirty brown, but in winter it becomes boiling white.
