Zac and Finley are up against it at the wildlife hospital. Can they get some dozy ducklings off dry land and onto the water? Alex and Josh dig in at an animal sanctuary. Can they handle the load when they have to clean up after mucky Mak the Exmoor pony, and will they get Rosie the bulldog jumping her way to freedom? And Dick's a shepherd for the day but can he get sheepdog Dom under control?
