What can I give my goose,large area with bone exposed at tail to keep from getting infection? He can walk and is drinking water,flapped his wings even tho there is a place there also torn up and the neck. Not bleeding(amazingly). I got there in time to see my neighbors four French bulldogs pulling out feathers( they came under her fence into my pasture through a soft place from the recent rain). Anyone know if I can get penicillin and give a shot in breast? Anything else?
