Yes! It is good you started him around neighborhood dogs already. Keep bringing him around dogs you know so his confidence can return. Watch CJ's body launguage while with other dogs. If he seems scared don't coddle him this will only reenforce his fear, correct him (however he is used to being corrected). Use rewards while around other dogs, whatever you use for rewards(verbal praise or treats). Dogs can become dog agressive after an attack and they will attack out of fear. It sounds like you are on the right track.
