Do you have a picture of the wound? Does it appear to be infected? Denegard is specifically for MG treatment, but Tylan can treat some other bacterial diseases. Many feed stores sell Fish Mox amoxicillin or injectable procaine penicillin G with syringes and needles. If the wound appears infected those may help, but usually topical antibiotics and wound cleaning twice a day may be all that is necessary. Use the antibiotic if you feel like using them, including Denagard if that is all you have. It certainly won’t hurt. Dog attacks are always iffy, since the chicken may die from no ovvious wounds, while terrible looking wounds may heal fine. It is the internal damage that we don’t know about. Sorry that you might lose her.
