Thank you so much for the information. I believe the vet thinks he swallowed too many pieces of his hoof & he's having trouble digesting it & it's giving him gas & such. He felt around & did not feel any blockages. I'm just supposed to give him a bland diet & watch him close. If he stops pooping or eating then I'm supposed to take him back, but so far no more vomit & he's acting pretty normal except for being tired. His little face just looked so sad this morning & like he was in so much pain. He looked a lot better at lunch. He did not have a temperature & he didn't throw up his breakfast, so I think we're on the road to recovery, but no hoofs for a little bit.
Sidenote: I think I have salmonella. I used an egg to make waffles last night I think might of been a bit old. I threw up last night & have felt crappy all day....so the two of us are quite a pair.
