     "Children should not be left unsupervised (无人监督的) to play with a dog." say experts in this

week's British Medical Journal. Their advice is part of a review aimed at doctors who deal with dog bites.

     "Dog bites and maulings are a worldwide problem, particularly in children." write Marina Morgan and

John Palmer. Every year 250,000 people who have been bitten by dogs attend minor injuries and

emergency units in the United Kingdom, and half of all children are reportedly bitten by dogs at some

time, boys more than girls.

     Accurate death figures are difficult to obtain, but in the past five years, two to three cases a year have

made news headlines.

     Based on the latest medical evidence, they advise doctors how to examine and treat a patient

presenting with a dog bite. They discuss the risk of infection and when to refer to specialist care. For

travelers bitten abroad, they suggest assessing the risk of rabies(狂犬病).

     In terms of prevention, they suggest that children should be taught to treat dogs with respect, avoid

direct eye contact, and not tease them. They should be taught not to approach an unfamiliar dog; play

with any dog unless under close supervision; run or scream in the presence of a dog; pet a dog without

first letting it sniff you; or disturb a dog that is eating, sleeping, or caring for its babies.

     "Dog owners also need to change their behavior", says Rachel Besser, a children's doctor and lifetime

dog owner, in an article.

     "It is clear that not all dog owners appreciate that children should not be left unsupervised with a dog",

she says. Just as some parents are obliged to take parenting classes, she would like to see compulsive

classes for expectant dog owners to teach them about the responsibilities of dog ownership. Educational

programs are also needed to teach children about some precautionary (预防的) behaviors around dogs.

      Finally, she would like to see animal doctors advising dog owners about bite prevention, and doctors

promoting bite prevention when treating patients who have been bitten by dogs.
