I think my duck got attacked by a dog, he came home (he is free range) and was limping badly and blood was coming from his chest/belly. How do I help him? It has been a day but I have not done anything thing and I don't want infections. What do I do?? His brother was with him when it happend but was not ingered, and he would not leave his brother wounded. He protected him for the rest of the day so I couldn't get a close look.
