Finn and Tyg can't seem to run far in the fields without stopping for a boxing match. It's better when Tyg is chasing Finn as he can't catch him easily, but their preferred game is Finn, who is by far the fastest, chasing Tyg, which means frequent bouts of mock fisticuffs which can get quite rough. So many K9 folk seem to post pics of their dogs actually running together as opposed to engaging in some kind of whippety contact sport that I'm wondering if my two are taking things to extremes.
