This is the heartbreaking moment an owner was caught on CCTV abandoning his dog on the side of the road. And the poor pooch looks completely lost after he drives away, slowly moving its head from one side to the other looking for him. Tazewell County Sheriff's Office in Virginia, US, released the video to try and identify the male owner, who was filmed tying the dog to a post. The footage shows him slowly drive up in a red truck, before getting out and leading the tiny dog over to a patch of grass. Wearing a loose-fitting blue shirt and jeans, he doesn't look back once as he walks away. The Sheriff's Office has posted the video on its Facebook page, sparking huge outpourings of love and sympathy from users.
