Now Even Wolves Are Using Treadmills!
Check this out. A wolf treadmill in Austria.
The Wolf Sciences Center wanted to explore cooperation and coordination between dogs and humans, as well as the differences in how dogs and wolfs can be trained. That required a very big treadmill that could fit multiple animals an humans. Wolves run in packs, so, apparently, the Center is training them to run in a pack on their treadmill.
Want to run with the wolves without getting bitten? Try the Wolf Sciences Center in Ernstbrunn, Austria. They sponsor Howl Nights too.
