I show show pigs for FFA, and our pens were 10x10 with cement flooring and a covered barn. We stuffed our pens with shavings for the pigs to be comfortable. They had fans, misters, automatic waterer, heat lamp, and were fed twice a day. I took my pig out and exercised him by walking every day. I washed my summer pig in the wash racks every day, because he LOVED taking baths and it was a great way to cool him down. There's a sand arena they can run/root around in while you're cleaning out their pen and getting their food ready. When I exercised, I'd either walk him in the sand arena to get that show feeling, or walk him around the barn in the grass for about 10-15 minutes. An yes, I taught my pig how to trailer by walking up the ramp. I inevitably taught him how to walk onto the slaughter trailer on move-out day, and got the compliment that my pig was the most behaved out of every singly one that loaded on the trailer. I took very good care of my pig and treated him like a dog, and he loved me. He was very smart and learned how to open his gate to his pen, the little rascal. The first picture is the day I got him, and the second picture is a couple months later rooting around in the arena. I miss my Ossi.
