Bernaise, our female Silver Appleyard, was attacked at some point during the day, yesterday. We believe it may have been a raccoon (probably not a weasle since she's full grown) that was subsequently run off by our guardian dog. We treated her wounds (all head wounds) and stabilized her. In the past, our farm vet has given us injectable antibiotics. 1 injection initially and 1 more 3 days later. I don't know the name of this magic drug, but it always works. As luck would have it, today is Sunday and our farm vet is unavailable except at emergency vet prices, which are unfortunately prohibitive. I know that penicillin is available at the farm store, but I don't know what dosage to give her and for how long. Greatful for any advice on dosing.
