Lulu, a goldendoodle who works as a therapy dog, lolls on the lawn outside the Ballard-Durand funeral home in White Plains, N.Y., on Thursday, June 4, 2015. Funeral homes are increasingly using dogs to comfort mourners. Funeral directors say the dogs, usually trained therapy animals, can lighten the often awkward, tense atmosphere at a wake or funeral service. (AP Photo/Jim Fitzgerald) (AP Photo/Jim Fitzgerald)
