How do wolves bring building material home??

I was exploring and got the encounter where you go West and get a building material. What came up for me was a large rock. I had to spend a minute imagining how my lead wolf got the thing home. I'm picturing this rock like the size of a big watermelon or pumpkin, and this wolf just half dragging, half rolling it along, and the mental image made me happy. Like, I get how the wolf brings home the big leaves. That's pretty cute but simple enough. But the logs and large rocks are fun to imagine

My lead wolf dragged home an entire bison carcass the other day. All the way from the prairie to the coniferous forest. Maybe leads get magical teleportation powers? 

Hahaha I love it. Imagine your lead just rolling it along with their nose like rolling a giant ball or something. Teleportation would probably be easier
