S1, E4: On Baby Planet, the best care in the world wont stop nature taking its course whatever the outcome. However even the darkest cloud can have a silver lining. In this programme keepers struggle to save sixteen hunting dog puppies after their mother dies; sadly only six make it, but they have a bright future as part of a new pack. We go home with a rejected Barbary lion cub where she finds a new canine companion, and see how a baby White-cheeked gibbon keeps staff guessing about its gender. In South Africa abandoned Wattled crane eggs are put in an incubator very few hatch out, but the efforts to save this threatened species must go on.
