Joann Cencula of Doggy Heaven holds photos of her beloved dogs that have passed away, at her home in Wickliffe, Ohio. The dogs in the pictures are, from left to right, Roxie, Hobo, Mongo (black dog at top), Freeway, Shelley, Beemer (obstructed except for eyes), Kahn, and Hemmie (top right). When pets die, humans can feel a spiritual and seemingly unbreakable bond. Nowhere is that more apparent than in the increasing number of pet obituaries springing up on the Internet, in some newspapers and on social media sites. (AP Photo/Amy Sancetta)
