Izzy started to cause some real trouble for my barn owner by digging some serious holes. He dug down so deeply that he found the water lines. The first time he did it, we were able to cover the hole with his water trough. For a while, his holes just revealed dirt, but he eventually found the water line again and broke it. Miraculously, that line was dead, but the one immediately beneath it was not.
My barn owners didn't want to take any chances. They filled the hole and kicked Izzy out. Not to worry, he actually got upgraded to a roomier stall and paddock which we hoped would allow him to burn off some of his excess energy. In case you're wondering, he gets ridden and/or turned out daily. Twenty-four hour turnout isn't a possibility.
Unfortunately, the hole digging began again which required me to come up with some new toys. That's where the tires come in. I've also started to throw his "free feed" hay (right now a coarse and stemmy three-grain hay) out in the paddock so that it more closely resembles grazing. I had been throwing it inside near his cube bucket, but this seemed a more playful solution.
I've also ordered a 55-gallon industrial plastic drum for him to roll around which I am picking up this afternoon. Now that he has a much larger paddock, he has room to kick and roll around a toy as big as a barrel. It was pretty pricey, so I hope it will hold up to his shenanigans.
I am telling you, this is the most destructive "puppy" I've ever owned. None of our hole-digging, hose demolishing, plant-eating Labrador Retrievers have anything on this horse!
