Fox in the park

This morning, Dylan and Flash disappeared into the distance on the playing field. As it was of course dark, I couldn't see what they were after, but after a while I could hear fox noises. I went up to where they were and sure enough, there was a terrified fox being "attacked" by Dylan and Flash. Of course, Dylan and Flash are muzzled, so couldn't physically hurt the fox, but the fox was exhausted by the time I got to them. I pulled the boys away from the fox and I hope he is ok. He looked quite young...
