In this July 25, 2012 photo, Pablo reaches out to Juci, a Parson Russell terrier, held by his mother as an American cocker spaniel named Lancelot lays under Veronica Pardo, left, who owns the dogs, during the dogs weekly visit to patients at the SOLCA hospital in Quito, Ecuador. Pardo says her dogs are used every Wednesday to cheer up the most discouraged of the patients. Hospital workers began to notice that on Wednesdays fewer children had to be kept over because of problems after chemotherapy. Doctors found that youngsters' adrenaline levels rose from being with the dogs, boosting their resistance to chemo's side effects. (AP Photo/Dolores Ochoa)
