Can you help me please ?

Don't pee on my leg, and tell me it is raining:

= I do not DO people's HOMEWORK. Do your OWN work! You'd KNOW the answer, if you bothered to READ your class assignment and/or assigned book or books.

Then Jamie should be trained not to annoy dogs

Woah, too deep for me. All I can say is it's a pity he was bitten by any dog (how did that happen - circumstances?) but if you sit down and take the time to talk to him about what happened, why and how he can avoid it happening again, he should understand and lose the fear of dogs he now has. All too often I've seen parents reacting to even seeing a dog on the street, instilling unnecessary fear in their kids which is very sad. It's up to YOU to help him understand that by no means are all dogs to be feared, just respected so he doesn't pile into a strange dog. It would be very sad if he remains fearful of all dogs on the basis of one occasion that he was bitten. And it would depend on the circumstances there too.
