If they REALLY cared about the pup, they’d have given him mouth-to-mouth.
It didn’t need mouth-to-mouth resuscitation, it was breathing on its own, just couldn’t stay afloat in the water because of its injuries.
Look for “2 foot pup” to be voting in the 2016 election.
Humans can’t reasonably save all wildlife from natural predation, no matter how cute the offspring are. Left in the water, the injured animal would soon have been finished off by its preditor species. It’s a cruel world.
