In this Friday, December 5, 2014 photo, Iranian volunteer Rana Ashough and her colleague groom a dog at the Vafa Animal Shelter in the city of Hashtgerd 43 miles (73 kilometers) west of the capital Tehran, Iran. The shelter struggles to find homes for dogs, with only around six being adopted each month. Iranians, like many other prospective dog owners, prefer purebreds to strays, something the shelter is trying to change. (Photo by Vahid Salemi/AP Photo)
