Hey guys, tonight I got home and Chief was laying down. He had been laying down before I left home, and it's not like him to lie down that much. When I fed him this evening, I went out to the yard and I was calling him but he wasn't moving, so I opened the gate and the sound of the chain woke him up. When he finally got up, he didn't move, and he was very slow and calm. I poured his food and he just sat there yawning over it- he usually eats like there's no tomorrow. I went out to check on him about 15-20 mins later, and he still had quite a bit of food left. He would have usually been done by then. I ran out of feed yesterday and could only give him half a scoop (usual is 1 & 1/2), and a flake of hay. This morning I was stil out so I didn't give him any feed, but extra hay. Does anyone know what might be going on?
