I local person who adopted a full size donkey took him to be gelded to an experienced horse vet yesterday. He was up, got into the trailer, and seemed okay. He did drink a lot of water last night, which seemed unusual. She went out this morning and he was dead. She called the vet and was told "sometimes these things happen". So, he must have had some underlying issues, to have been so thirsty? She's had him several months. Pretty shocking.
