I’m guessing he did or you or the video would mention it
Why would you assume that? I have no idea. I would be fine trying to dig up the rest of the clip to see context, although I don't know if I would succeed. Given his reaction I would be pretty surprised if he fixed it.
This video doesn’t show anything like what you’ve described. All I could tell was that the dog yapped at one point and… that’s it…
You can literally see the shock collar box on her at 0:13 when she turns away to go back to the platform. He also claims that she "clipped herself", when he wasn't looking at her and would have no idea why she suddenly gave a big sharp yelp right at the same moment when he reached for something off screen.
If he was telling the truth, he would say "I have no idea why she made that noise, she's a big baby" or something. That is literally the only explanation that he would have that even could be truthful. The fact that he even has an explanation for what happened that made her yelp means he is lying.
People on Reddit have also slowed down and brightened the footage, and it's very clear that she didn't bump herself or anything on any object, that just suddenly out of nowhere she made this sudden yelping noise and also changed her mind about wanting to get off the little platform and go walk around.
You can draw your own conclusions of course but I am not sure why people could see this and come to any other conclusion.
Seriously. I have some politics that are more-or-less similar to some of his politics, so I was sort of predisposed to like him, but almost every video I have seen of him makes him look like such a massive childish cunt that I can't understand why he has a following. Just hearing his voice whenever he gets challenged or corrected on something is like hearing an angle grinder.
