I lunged him today and it was freezing outside and he broke a sweat and I walked him around the round pen once to let him cool off a little then I brought him outside the roundpen to eat a little bit of grass so I could wait until the cute little kids rode by on their cute little horse...then I walked him back down to the first field and let him take take a couple of chunks out of his grain bucket and by then I kinda realized I probably should have let him cool off more than I did so I took him away from his grain and walked him for a few more minutes and then let him eat some grass for maybe five minutes and then I let him finish off his grain. He didn't seem sick when I put him back in his field, but I'm still really worried, I was listening to his stomach to see if I could hear any gurgling noises and I did hear that (I was taught the hard way before- when I had my Thoroughbred- and learned a lot about colic and I learned that gurgling in the stomach was a good thing and he passed gas when he was walking towards the hay which is also supposed to be a good thing), he wasn't pinning his ears back like he was sick or anything and as we were leaving he went straight to the hay and started eating it....oh yeah...plus we give him beet pulp, which we hear is supposed to be good in helping them digest so that might help to prevent colic??? Do you think he might get colic because I didn't cool him down properly after exercising him. After exercise we fed him a scoop of grain with a scoop of beet pulp??? Please let me know any information that might help
