Bloat is very scary. My experience with it was with a pony. We came out to my friend's stable and noticed Suzie (the pony) was laying down. We thought, oh how cute. But then we realized she didn't look so good, and she wouldn't stand up. And we realized how FAT her belly looked, unnaturally large to the point that two 13 year-old kids like us even not knowing a thing about bloat could see that there was an emergency before us. We got my friend's mom to call the vet out and meanwhile he said to get her up and keep her moving. He got there pretty fast and down her throat with the tube. But her gut was so twisted he couldn't get the tube down. Poor Suzie was so scared and we were so scared and knew she was in horrible pain. But unfortunately it was too late to save her, and she was in so much pain that the vet had to put her down right there. My friend and I took off running because we were way too young to see that. I am sick to my stomach even thinking about it now. It is a serious and fast problem. We never really knew what caused it for Suzie, but the vet suspected she has been rolling around after drinking some water, and the stomach turned over trapping gases in there, leading her to become completely bloated.
I have deep sympathy for anyone who has had to experience this with any of their animals, it affected me so deeply even though it wasn't my pony that it happened to. I'm glad everyone is sharing information and that website posted by Oreo's dad is something we should all read.
