No Surprise: Wild Dogs Act Wildly

In Christine Dell'Amore's article "Pittsburgh Zoo Tragedy: Why Did African Wild Dogs Attack Boy?" (Nov 5th, www.natgeo.com) the author is trying to find an answer to the terrible event that led to the death of a 2-year old child.

An expert in this particular dog species, Rosie Woodroffe (London's Institute of Zoology), says that she "very much doubt[s] that this was a predatory attack." She thinks that the natural curiosity, in addition to the loss of fear to humans produced by captivity, made the pack approach the kid in an inquisitive way, but once the dogs saw that the little body was moving, they might have felt instinctively driven to bite him.

A lot of questions and speculations have arisen in terms of the parents responsibility in this catastrophe, and I'm sure that the parents themselves will be dealing with this issue for a long time. What feels pointless and almost absurd to me is to try to explain why the wild dogs behaved this way. Isn't "wild" very close to "unpredictable"? We sure can expect wild dogs to do wild things.
