Round 'Em Up

In the summer we got Arlo a treibball which people recommend for herding dogs. Initially he played with it inside, where we protect it bashing into things, when we tried it in the garden it often just ran down the hill, but now we have gates he pretty much keeps it in this area. It's a heavy ball and treibball is supposed to be done with his nose, so instead he uses his shoulders, while trying to bite it. It's not 100% treibball, but it keeps him busy and boy does it tire him out, he does enjoy it.
