"to the dog shall you throw it": "to the dog"—as to the dog (i.e., anything like a dog.) You say this, but perhaps it is to be taken literally? It is, therefore, written (Ibid. 14:21)"You shall not eat any neveilah, etc." (but you may derive benefit from it). Now does this not follow a fortiori, viz.: If it is permitted to derive benefit from neveilah, which causes "carrying uncleanliness," how much more so, from treifah, which does not cause "carrying uncleanliness!" Why, then, is it written "to the dog shall you throw it"?
