Kate Humble and Ben Fogle embark on the final episode in this series of summer specials at Longleat Safari Park. There is huge excitement amongst the carnivore team as it seems the European wolves, captured mating earlier in the series, have given birth to pups. But wolves are notoriously secretive, so keeping an eye on these new arrivals is far from easy. When first-time dad Django oversteps his parenting role, the keepers have no way of knowing if an injured pup has survived. Ben joins the team as it takes an extremely rare opportunity to enter the wolves' den to check the health of their new brood. Meanwhile, the hoofstock team are on a mission to toughen up their Wiltshire-raised giraffe by introducing a thorny feeder inspired by a trip to Africa, but will these gentle giants be spooked by this new invention? Jean Johansson helps to get Newt the abandoned wallaby joey working out before a spot of weight training with a pair of cotton-topped tamarins.
