Please help me. My 4 Week Old RIR was bitten by a dog this evening. It is above his left wing. Wound a little smaller than a dime. Skin is missing and muscle is visible. Could possibly be a puncture wound.However I do not see damage/trauma to the muscle tissue. The chick appears to be in no acute distress. It is calm and resting. Breathing is normal. I have separated him from the others to avoid pecking. He is on a bed of pine shavings with food and water. I have never seen this dog before not do I know who owns it. What should I do? What medicine do I need? Is topical medication enough? I am sorry I can not upload pictures at this time. I fear that what I need will not be available to me since today is Sunday. Anyone with any advice would greatly be appreciated.
