I can help you with the wild dogs...Harry, Barry, Larry and I can't think of the last one (use your imagination 'cos it rhymes but I really can't think of what it is) and they are all brothers too.
This photo shows the covered bridge that is deemed a "walk-through" feature of the exhibit. Lion Park opened in 1967 and I wonder if the bridge is a unique feature of this zoo as I cannot recall seeing another carnivore viewing area patterned on it. Is there a separate exhibit on the far side of the bridge? If I remember correctly it had African wild dogs in it on my 2007 visit.
@Animaldude Zuri, Chaka, Harare and Moja. They were born in a litter of 5.1 at Melbourne Zoo to Tsavo and Jespah 31/12/2000. The males are now all deceased; while the female (Jarrah) is at Werribee Open Range Zoo.
