The dog park is too far away on foot to bring Donna to, unless Mr P is available to drive us there. I did walk Donna there before, but she ended up totally tired and laid down to rest every time I stopped walking on the way home.
But actually there are at least a couple of big grass patches in our vicinity that I can bring her to to just run free for a bit. That is, if I can successfully train her on invisible barriers to keep her safe, since she can sometimes be so easily spooked.
But first I need a long line.
P/s: Wish I had seen this video when we were getting Donna to respect the no dog zones in our house!
