If you are medicating a food animal, you should have already asked a doctor about the medicine you are giving that animal.I don't disagree; it just seemed the sort of question you would want to ask a doctor.
Reminding people of simple grammar does not require the intervention of a doctor.
If you are trying to somehow claim that the horse goo you bought at the feed store isn't actually for horses, and is instead for humans, then you very much want to be in contact with a lawyer, rather than a doctor.
