I've carried a 120 lb dog, writhing and yowling, for a quarter mile at a jog. Pure adrenaline though, I saw a boar and didn't want to see him gored, he was still a “puppy” being a Lab, despite being two years old and quite the big boy. My back was sore for days, but I'd do it again.
Anyone who'd take their dog into harms way and abandon it is a poor excuse for a human being, imho. There were other hikers. There was help if he cared to ask. He didn't, just left her there, abandoned and cold, to die. Then, after the danger had passed, for days, he didn't go to retrieve her.
He deserves to be charged with animal cruelty because what he did (and didn't do) was cruel to the point of depraved indifference.
Seriously...I think I love you.
