It’s a dog-eat-dog world out there, even for the Smithsonian’s adorable newborn wolf pups.

“The mom tends to move the pups a lot, which can hurt them, and sometimes they do end up eating the pups,” a research biologist told the Smithsonian’s “Around the Mall” blog.

The Front Royal, Va.-based Smithsonian Conservation Biology Institute has tried to breed this threatened species of wolf in captivity since 1975. In their natural habitat, central South America, about 20,000 of their kind are left.

The four newborn pups bring the Smithsonian’s total number of maned wolves to 12. Two wolves live at the National Zoo’s “Cheetah Conservation Station.”
