my hen was bitten

Came home today and my dog was going berserk. I have trained her not to think of chickens as food but she loves to play with anything fluffy. She led me to my only RIR hen petrified with fear next to my garden, I new my dog tried to play with her when she got out of the run and bit her. After looking her over I only saw one flesh wound, barely punctured the skin almost no bleeding. I cut the feathers from around the wound and disinfected it and put her in the hospital ward. Anything else I can do, I already lost one rooster to an infected bite.
