Burdened

Lycaon pictus
 
This alpha male is the leader of his pack, and is responsible for feeding and guarding 12 pups - all in addition to keeping the rest of his large, mischeivous pack in line. From his bearing, we inferred a resigned vigilence to his duties. This incredible species is sadly threatened on all fronts, even in the last decade we've witnessed them disappear from areas they once roamed.
