There are actually a variety of organizations that have canine weight pulling contests, though this is the first I’ve heard of a multi-event contest like this. That 1000lb figure isn’t theoretical either. Apollo was training for IWPA pulling, and managed 600lbs at the age of 9months and doing so like it was nothing, I was ready to pull the plug cause I was worried it was to much weight on his growing frame, but he didn’t even flinch. And he wasn’t even GOOD at it. Dogs who’d been training for a while were pulling 1000lbs plus in competitions in almost all of the weight groups. Sound insane? Go here and look at the contest results. Dogs weighing as little as 30lbs pulled over 1000lbs.
I’m not sure if it’ll replace dog fighting in the culture, but I like the concept. More power too them.
