My mare loves to play with the dogs. My dog will chase her, so he is not in the pasture with her, but they will play across/thru. They will run up and down the fence line, one barking and growling, the other bucking, rearing, squeeling, like she's attacking a pack of coyotes. She does it with my parents dog also, and just last weekend put both feet thru their privacy fence.... so I'm buying new wood, and replacing the thermometer that was on the fence. But since then, she stays far enough away that she doesn't touch it.
Of course, by the time I thought "camera" they were done playing lol
