heart failure

Fred looked out the window and says to me "you have a weird horse". I said why? Freds reply was " Because he is laying down with all four feet in the air and not moving. I jump up to go look and open the window and call him and yell , clap my hands and he still doesnt move , Bud starts to walk away and he still doesnt move..... I'm thinking I have a dead horse. I have never seen a horse lay like that. I grab my coat and go down to the barn as fast as i can on the snow and lo and behold both he and Bud are standing at the gate looking for food!!! I guess he was just taking a good nap the little goober. Dont want to have a scare like that again.
