The abilities of dogs have allowed them to help other species of animals in a variety of ways. Dogs can sniff out endangered species or use their noses to find invasive ones. They can track lost or injured animals and they can protect them from potential predators. They can even deter other animals from visiting areas in which their lives would be at risk.
Scaring bears away from areas where they are not welcome may seem unkind but the dogs who do so have saved the lives of many of those bears. Bears that are scared away are safer than bears who keep visiting certain areas.
