Chicken Little's rump is infected from a small dog nip. It closed up rapidly, and became infected. How much penicillin and how often? I am very worried- the rump blowing up and turning red. I have two days of 1/3 cc penicillin into her, and I am wondering if I should have hit it harder- like 2x a day?. I will know tonight if she is turning around. Her behavior has been normal. Also, wont it abscess & drain on its own if that's what's meant to be? I have cleansed the wound initially with betadyne soap mix, etc. but the puncture went deeper obviously.
