my dog got ahold of my muscovy hen last fall and took a hunk out of her breast right by her wing. I was devasted but you know what?? She healed beautifully and is fine now. As long as my dog is on chain, he is still a puppy at 10 months and still in training, he is fine. he only wanted to play. He never kills anything that is why we turn him loose only when the poultry are in the secure coop at night and he goes on patrol. During the daytime, they are in his dog house and all around him as he sleeps or just lies there not paying any attention to them. Now my duck had a nice hunk out of her and she did just fine, no indentation or anything. If you have access to a puffer antibiotic than that would be wonderful. It is called Neo-Predef. I get it from the vet for 9.95. Yolu just "puff" the powder on the injured part and leave it alone. I have used this on several of my chickens, etc. and it works fine for poultry. good luck and keep us posted.
