I would not allow him to run after and chase other dogs. The whole dog-park scene may not be in the cards for this dog. But, if you do take him to classes where he and the other dogs are under control, he will learn how to behave around dogs that are under control, and taking him to the vet or even to a dog show will be possible without his reacting like a nut. Getting a CGC on him should be possible. Doing an performance event like obedience, schutzhund, tracking, and any number of other things should be possible as well.
