Before buying a dog, many people picture an idyllic scene of children playing happily with their new pet, learning to care for them and enjoying the benefits of outdoor exercise.
But children and dogs can be a difficult mix. In 2005-06, almost 900 children aged nine or under were admitted to hospital after injuries caused by dogs.
It's enough to have prompted doctors to recommend that children shouldn't be left alone with dogs.
As well as supervising your children when they're with a dog, you should teach them to:
Stroke the dog gently on the head or chest without 'hugging' it around the neck.
Avoid staring straight into the dog's eyes because it may think this is threatening behaviour.
Avoid running and screaming around the dog.
Leave the dog alone when it's eating or sleeping.
Treat the dog with kindness and respect.
To minimise the risk of aggressive behaviour by your dog:
Do some research before you buy and find out which breeds behave best with children.
Buy from a reputable breeder.
Take your dog to a formal training class and teach it to behave well around children.
Make sure your dog has a 'retreat', such as a bed.
Avoid giving your dog toys that resemble children's clothes or playthings.
Don't allow your dog to play rough games with adults that wouldn't be safe with children.
If you already have a dog and are expecting your first baby, you should take precautions to make sure jealousy doesn't provoke aggression:
Change the dog's routine ahead of the baby's arrival so it becomes used to its new regime - it may have to cope with fewer daily walks for the first few weeks, for example...
Encourage the dog not to go upstairs if that's where your baby will be sleeping.
Test your dog's reaction if you lavish attention on a doll wrapped in a blanket.
SafeKids recommends keeping your dog away from your baby for a few hours after you first come home. After that, introduce the dog on a lead.
Most parents have known that nervous moment when a strange dog looms, especially if it's a big or boisterous animal.
In any situation where your children might come across a new dog, ensure they:
Ask the owner's permission before approaching the dog.
Allow the dog to sniff the back of their hand first.
Avoid running or screaming if they're frightened, instead they should stand still, fold their arms and stay quiet.
Don't at the dog, take its toy or bone, or put their face close to the dog's
Clean the wound with running water as soon as possible for ten minutes to reduce the chance of infection.
Cover it with a non-stick sterile dressing.
Stop bleeding by pressing firmly on bite while holding it in the air, if possible.
If there's a lot of bleeding or the wound is large, deep or dirty, see a doctor or nurse.
Animal bites abroad are potentially more serious because of the risk of rabies in some countries. Seek medical attention as soon as possible
