If a pack member is lost, the pack will howl to help him find his way home. They howl as a means of communication, whether it be for a serious reason or simply a display of happiness Wolves breed in the winter and have their cubs in the spring. Again, the pack as a whole cares for the young ones. Usually the cubs will stay with the pack at least until they have matured at two to three years of age when, occasionally, they may decide to leave. This is how packs grow.
Most wolves are a part of a pack for a lifetime.
In their senior years, the alphas see to it that they are well cared and provided for. So, we have a family unit with a male and a female leader. They love each other and are committed to each other for a lifetime. They eat, sleep and play together. They get food as a family unit and care for each other.
