Animals can make a huge difference for people recovering from illness or injury.
Many therapy dogs undergo extensive training for the job, but sometimes it is a skill that just comes naturally.
Hans the dog is everyone's favorite physical therapist.
An accident more than a year ago left him paralyzed, but don't tell him that.
Research shows animal-assisted therapy can reduce heart rate and blood pressure, lessen anxiety during medical procedures, increase long and short term memory and motivate patients.
But Hans is a special case.
Though he is not a certified therapy dog,his disability reminds patients of everything they can do. Han’s owner, Anne Huber explains, "Petting him, they have to really control the movement of their hands, they have to be gentle. It makes them really concentrate on their hand movement."
Hans' disability did not just enhance his life.
It inspires patients to restart their lives, limbs and hearts.
