Imagine waiting at the airport after having missed your flight, had a flight delay or you’re experiencing your usual fear of flying. Then suddenly comes a tail-wagging pup, dressed with a brightly colored vest or bandanna with the words Pet me!. As the dog comes towards you or you towards it, a feeling of relief from your anxiety and stress will begin to surface. When your pet, hug and kiss the dog for a bit, the stress would be gone. That is the work of therapy dogs in airports and studies have revealed that such interactions are of exceptional health benefit to humans. For example, simply petting a dog is enough to lower someone’s blood pressure and relieve them of fear, stress, and anxiety.
