Jesse is currently 5.5 months old has been socialized since he was 8 weeks old, with people of all nations and ages, animals of all kinds, places, everything was going good till last Friday when neighborhood kids came over 8 of them in total and surrounded Jesse, and he accidently got hurt by a 5 year old girl. Now when he sees kids he hides behind me or tries to crawl up on me. I have taken a new way of trying to deal with it, I have gotten really good dried chicken pieces (he loves but doesn'tget very much of) and I hand them out to kids and get them to give it to Jesse (open handed) while making him do something (ie. give a paw, sit, down). After days of doing this, he is only ok when getting the treats but before and after that is done he hides behind me. Anything else I should do about this?
