We have an 18 yr. Old gelding that got into the feed room one week ago. The vet tubed him and we withheld food for 24 hrs., gradually getting him back on a normal feeding schedule. He was fine until this past Wed. He tried to kick the farrier, which he has NEVER done! When he went to eat, he wouldn't lower his head. He acted very lethargic and just didn't seem right. It was very hot that day - 101 degrees - so I called the vet and he did a complete physical exam, including internal exam. He suspected heat colic, so he tubed him again. We stalled him for 2 full days with gradual food increases which we made very mushy. He still acts like it hurts for him to lower his head, though his appetite is fine. He doesn't seem his usual self, still very sluggish.
Any ideas? I talked to the vet yesterday and he isn't sure what is going on. I am so worried that I may find him down and not be able to help him. :(
