Dog Left At Shelter Sees Her Family Come In To Adopt New Dog

'With her fast wagging tail seeing her owners Zuzu lit up like a Christmas Tree. She looked like the happiest dog. Yeah, she's going home,' wrote shelter worker Desi Lara on Facebook, who also took video of the heartrending scene. 'But no. Talking to her owners they told me they were not here to reclaim her, they were getting another dog.'
