Anyway, she got to close to a porcupine and got the quills in her back leg. We got them pulled out, and sprayed some ointment on to prevent infection. Now I'd like to give her some Pennicillian to help with infection prevention, but am uncertain how much to give, and for some ODD reason the bottle doesn't say. So what do ya'll think ? And how long do I do the shots ? Is it 4 days ? I can't remember.
