In this picture taken on Sunday, March 5, 2017, veterinarian Hamid Ghahremanzadeh, chief of Aradkouh Stray Dogs Shelter plays with some of his charges on the outskirts of the capital Tehran, Iran. The shelter has been hired by the Tehran city government to take a new, more humane approach to deal with the burgeoning problem of stray dogs in the capital. It’s a sign of changing attitudes among officials in a country where Islamic authorities long saw dogs as “un-Islamic” and would at times confiscate them from people who kept them as pets.
