We run doggy day care for a few dogs at our place, its great! They have a good run around the field, as well play with us and the other dogs if they want to. If we're not too busy we throw in a bit of basic obedience training but most of it is just exercising them and making sure they're having fun
We're not on a big commuter route so we don't get too many but its nice with the few we have got.
