It's been raining for about 12 hours straight. I finally took pity on the horses and moved them into the pasture with the shelter. I even put hay in there for them. But they had no interest in getting out of the rain and immediately settled down to grazing the new grass that has emerged since the end of the drought.
Not so the dogs. They had fun running around, and then they said, "Yikes, let's get out of the rain!" and they went to dry themselves off on my duvet. Thanks, guys.
