Humans have lived with dogs for many thousands of years - at least 12,000 and perhaps up to 100,000.

Given that history, it's no surprise that the human-animal bond is strong, and research now suggests it's more important than we thought. Owning a dog or other domestic animal can boost mental and physical health.

Someone who has had a heart attack, for instance, has a four per cent-improved chance of survival after one year if they own a pet. Pet owners don't suffer as badly from blood pressure increases due to stress, and they're less likely to suffer from cholesterol problems and cardiovascular disease than the non-pet-owning public.

Studies of school children have revealed that pet-owning kids had higher self-esteem and found it easier to make friends and. As they moved into adolescence, they also had a more positive outlook on life than non-pet owners and were more caring about community safety.

The message has never been clearer. Pets, especially dogs, make us healthier, more caring, receptive and friendlier. Where would we be without them?
