My explanation is that there really isn’t enough evidence to say exactly what happened to make her act that way. She could have hurt herself or got startled or something else.
Why is it reasonable to you that Hasan had a ready-made explanation for what specifically had happened?
Most of why I think this is suspicious is Hasan's reaction and explanations for things being obviously dishonest. Saying that Kaya "clipped herself" is one example of that. It (and his overall reaction on stream at the time) seem like a very weird way to react to your pet suddenly showing that she's in pain.
I believe he showed that he has a collar which vibrates and demonstrated it on stream. It possible that the collar could also have a shock setting but that’s not proof he uses it that way when training.
I agree with all of that, sure. It doesn't really address the question. It's not that it's "possible" that the collar had a shock function -- it 100% had a shock function, and then he covered up the shocking parts with tape and claimed that it only had a vibrate function. Isn't that a weird thing to do? Or do you not think factually that all of that is how it happened?
Since this article there have been no supporting eye witnesses and no reliable secondary sources supporting the shock claim.
I mean, there have been no supporting eye witnesses and no reliable secondary sources supporting the vibrate / dew claw theory, but that doesn't seem to be stopping anyone. Most of the reason I am strongly anti Hasan on this issue is (a) just observing how he interacts with Kaya and other dogs (b) the fact that he's clearly being dishonest when he speaks about the issue.
Do videos like him pulling the other dog by its tail not bother you? Like would it ever occur to you to interact with a dog that way? For me it would not, and I think if someone near me did it I would yell at them.
Edit: Oh, also, why do you think Reddit is deleting this? When did they delete the debunking? The "debunking" video is literally still the top pinned post on Hasan's subreddit right now.
