The hyenas might have been in here at one point, as I think that they have had 3 different exhibits at the zoo. This striped hyena and new guinea singing dog exhibits both appear to be similar in style, but the dogs simply have much more vegetation.
@Osedax San Diego Zoo doesn't have the species any longer, but plenty of other U.S. zoos have or had them recently. Wildlife World, Pine Mountain Safari, Great Plains, Catoctin, Miami, Claws 'N' Paws and a bunch of non-accredited zoos around the country.
