The endangered hunting (or wild) dog is quite rare--you typically do not see them in Hluhluwe-Umfolozi.  These animals are the size of German shepherds and travel in small packs like this one (there were about 5-7 of them).

When we came across them, they were tracking a wildebeast (gnu) about 200 yards in the distance.  When the dogs saw us, they broke off the hunt and began playing in a large field.  At first we thought they were jackals, but when we checked our guide book later that evening, we found out we had a special treat.

Surprisingly, these were the only predators we saw in Hluhluwe-Umfolozi (birds of prey notwithstanding) that year.  The dense foliage and our lack of wilderness experience may be the reason.  For all we know, we passed right by a pack of leopards without even knowing it!
