CRITICAL CONDITION, he should be in ICU. his chances are very slim. most likely, euthanasia will have to be carried out if the x-rays show he is paralyzed. depending on how he was hit, if it was in the chest area, the pressure could have caused some bursting of blood vessels in the lung area/chest area causing blood to come out of his mouth. or it could be his tongue as you said.
hopefully, the little guy has been stabilized allowing for more tests, but his chances are still slim.
