Try not to over-react when your dog over-reacts. Just tug on the leash and keep moving. Do not stop and let the dog get into his routine. A little tug and say, "it's only a dog," or kid or whatever, in a pleasant normal tone.
Keep walking with your dog. He had a bad experience, but now he needs to get over it. No coddling. Protect him. No baby talk. And if you are nervous, suck on a mint.
That might sound like weird advice, but many obedience people know that dogs key in on us. When we are nervous, our breath changes enough so our dogs can mark the change and sucking on a mint can make a difference.
Keep your voice up beat, and happy, keep your pup moving. No nonsense. It's just a dog, and move on.
