I just tried to watch Dog: Impossible. I was really looking forward to it. But I couldn't even get through the first episode. This guy does not understand dogs! He's danging a dog by her collar, hanging her by the neck? What the hell??
When the blue heeler greeted him, she was wagging her tail and showing all the dog signs of being friendly, and he read her as terrified and aggressive? Dude himself seemed really fearful. By the end of the first scene with her, he had dangled her by the neck enough times that her body language had totally changed to terrified and withdrawn. he read that as her relaxing. I read it as her giving up.
I beg anyone who wants to understand dogs to read Turid Rugaas's very short book "Calming Signals".
The first dog, Lou, who was afraid of collars? Maybe they can try a harness? Those don't trigger the same constriction around the throat. I was SHOCKED that the show was using choke collars and yanking the dogs around like that. Aside from being a sign you are dominating and fearful yourself, you can seriously damage the dog's throat, bruise their thyroid gland, and you are undermining the spirit of cooperation and respect you claim as your goal.
You can use positive methods to establish trust and turn a fearful aggressive dog into a love muffin, without choking them. I did it with my neighbor's dogs who were growing and lunging and nipping at passersby. In a few days they were total love muffins. Use calming signals, and positive reinforcement. Be loving, not scary.
I was really looking forward to this show, and what he says about his attitude seems to be the exact opposite of what he actually does. So disappointing!
