Hi,
I am very sorry about the accident. Please get your vet out there and put him on an I.V.
Also, if you have a Vet Shool close enough, I would bring him there so they may throughly check him out and put him on the proper fluids. We don't waste a minute here, if something is wrong they go to the Vet School immediately. You will feel better and so will your steer...
Please let us know how he is.....
