Learn to Smile

Dogs are generally called “man's best friend”. They are loyal, funny and loving. They seldom complain and always obey their owners. People who have dogs seem to be happier and healthier than those who live alone. One reason for this is that people with dogs lead more active lives. Who can say no to a lovely dog when he pulls on your arm and asks you to take him for a walk?

Dogs are really amazing animals. They not only provide great help for humans but also offer emotional support. Think about guide dogs for blind people, or dogs that help people in wheelchairs.

However, it is the emotional side of owning a dog that has been studied in detail by Dr Julie Davis of Chicago University. I have interviewed office workers and farmers, policemen and construction workers," says Dr Davis. Everyone wants to talk about their dogs. Many people said they cried much more when their dogs died than when their parents did. They said the sadness was much deeper. People tell me all the time that they get more emotional support from their dogs than they do from their husbands or wives."
