In fact, research out of the Wolf Science Center has found that in some situations, these wild animals are actually more tolerant than dogs: Given food to share, dogs keep their distance from one another. Wolves bicker and snarl at first, then eat peacefully side by side. In one study, pairs of wolves or dogs must cooperate to retrieve a piece of meat; wolves work together effectively, but dogs were “abysmally bad,” says investigator Sarah Marshall-Pescini. When she tested wolf-human and dog-human cooperation partners, the pattern became clearer. Wolves aren’t afraid to take the lead, while dogs hang back and wait for a human to make the first move.
