85 million European households have a pet.  As this figure grows, so too does their role in people’s lives. Pets provide companionship, affection and protection and unique bonds are formed with owners.

In addition to being a source of love and friendship, there have been numerous scientific studies analysing the many ways in which pets are good for our health.

One of the more obvious health benefits of owning a pet is exercise - dog walking or playing with a cat are great ways to stay active. However, in addition to supporting good physical health, contact with animals is proven to encourage physiological and psychological benefits: reducing stress, helping to prevent illness and allergies, lowering blood pressure, aiding recovery and boosting chances of survival after a life-threatening illness.

As part of a wider role, FEDIAF members fully support research into the human companion animal bond and below is more information about some of these studies:
