Jacob,11, and his brother Jase Paradeaux, 8, learn about therapy dogs from dog handler Nancy Mittleman two days after the mass shooting at Robb Elementary School, in Uvalde, Texas, U.S., May 26, 2022. Jase, a fourth grader at Robb Elementary School, would have been in the class that was attacked, but this year, he was switched to another class and was spared the violence. The dogs, Exon, left, and Tarik, came from Crisis Response Canines out of Sicklerville, New Jersey. REUTERS/Nuri Vallbona
