Three wild dog brothers take a super-long walk across Zambia

Three brother African wild dogs walked over 2,500 miles in eight months from Kafue National Park to Luangwa Valley in Zambia, looking for land and mates. Zambian Carnivore Programme researchers say no African mammal, a furry warm-blooded animal, has been recorded traveling so far in one trip. Only about 6,600 adults are left, so the kind could die out.
