A therapy-animal trend grips the United States. The San Francisco airport now deploys a pig to calm frazzled travelers. Universities nationwide bring dogs (and a donkey) onto campus to soothe students during finals. Llamas comfort hospital patients, pooches provide succor at disaster sites and horses are used to treat sex addiction.
"Therapy Animals Are Everywhere. Proof That They Help Is Not." is from the July 02, 2017 Science section of The Washington Post. It was written by Karin Brulliard and narrated by Sam Scholl.
