Edna Colon, 18, said her mother, Elda Arguello, received a letter from the Animal Rescue League of Western Pennsylvania informing her that the male dachshund, named Tootsie, was found as a stray in Pittsburgh. The shelter tracked a microchip implanted in the animal back to Arguello and her family, WPVI-TV, Philadelphia, reported Monday.

Colon said several members of the family planned to travel to Harrisburg, Pa., for a reunion with their long-lost pet, who was about 6 months old when he went missing from Arguello's yard nearly five years ago.

"We appreciate the Animal Rescue League. If not for them and the microchip, we would never have seen Tootsie again. Because (the Animal Rescue League) understands animal lovers, they did all that they could to find us. We are so thankful to (the organization) and their work to get Tootsie back to our family," Colon said.
