Plot Synopsis

DOG: IMPOSSIBLE is a one-hour reality series that follows dog behavior specialist Matt Beisner and trainer Stef DiOrio, as they help some of the most dangerous, most aggressive and most misunderstood dogs in America. These are the dogs other trainers won't touch -- the ones that everyone else has given up on, and even recommended be put down. Beisner risks his life and limbs for these animals because, as he says, he used to be like them. After his own life was saved through personal transformation, Beisner rescued a dog, found his calling and dedicated his life to saving dogs that have nowhere else to turn. Beisner focuses on the unique needs of each animal, from detachment issues to aggression driven by fear. Even after all he's seen, Beisner still believes there is no such thing as a bad dog. Season 1 episodes include:

"The Tormentor" (September 2, 2019): Beisner takes on two cases, each on the brink of fatal encounters. The Presidents, a pack of five bulldogs, faces daily attacks within the home. Pax, a severely under-socialized pit mix, landed in the Top 10 Most Aggressive Dogs Beisner ever has worked with. Families are forced to make their worlds smaller for the safety of the dogs, so Beisner steps in with the hope of transforming lives.

"Don't Fear the Collar" (September 8, 2019): Beisner helps two dogs with wild backgrounds -- Agedashi, a previously feral blue heeler with violent reactions to strangers, and Lou, a neighborhood street dog with an extreme reactivity to collars. With animal services cracking down on feral dogs, Beisner must find a way to break through Lou's fear of collars before he gets captured and put down.
