Answer
There are many things that can cause limping from a fight wound.  it could be swelling around a nerve or a tendon or a ligament.  It could be an infection starting. There may have been a mild dislocation of a joint during the fight.  It could just be bruising.  You should have your vet check the dog to make sure that it is something that he will easily recover from.
