Joe Karl's life was turned upside down one day when his beloved dog Gunnar went missing. Karl and his family tried everything to find their cherished canine pal, but with no reports or sightings, they finally gave up. Around the same time, agents at the City of Pittsburgh Animal Care and Control were searching for a stray dog in a nearby neighborhood. Unfortunately, they were unable to catch the quick pup, but continued sightings over the months aided in their search. Eventually, they were able to bring the dog to safety and he was transported to a local shelter for care. That's when he was scanned for a microchip. The shelter staff discovered it was Gunnar! The poor pooch had been missing for 20 months. Watch Gunnar's emotional reunion with his humans below. I'm so happy that Karl was able to see his best friend again. I'm even happier that Gunnar managed to get back to his loving home. Far too many pets go missing leaving families without a clue about what happened to them. This truly is a happy ending for these best buds.
