Tucked away in Spain's Pyrenees mountains, patients at psychiatric facility Benito Menni stretch out across floor mats and stroke greyhound puppies Atila and Argi. Puppy love is part of the treatment for conditions such as schizophrenia. The facility, based in a town near the border with France, uses the dogs to help patients with intellectual disabilities and mental health conditions develop social skills and a sense of autonomy. Alongside misty views of green rolling mountains, petting sessions with the eight-month-old puppies have a calming effect serving as an emotional outlet for patients who struggle to connect with others.ÊPlaying with those who are more active and sitting still with those who find moving a daily challenge, the dogs tailor their behaviour according to the needs of their patient.

French BEA air accident investigators reported March 13, 2016 that a doctor had recommended that the German pilot who crashed an Germanwings jet into the Alps last year should be treated in a psychiatric hospital two weeks before the disaster. Prosecutors believe co-pilot Andreas Lubitz, who had a history of severe depression, barricaded himself into the cockpit and deliberately propelled his Airbus jet into a mountainside killing all 150 people on board.
