Seriously? We can purchase PenG at the local farm supply store.
ONE shot of PenG will not be enough. Might tamp down the infection for a bit but it will not get rid of it.
There are also different types of infection that require a particular antibiotics - PenG, SMZ, uniprim, oxytect, etc.
If the infection comes and goes - it may be something more serious deeper in the leg. Probably worth a vet visit.
