I find it strange this story seems to be getting so much traction in the media. I first saw it on a Forbes article, and now PETA has made a statement.
Idk if it was a shock collar, vibration collar, or if the dog got a claw stuck or whatever. In the clip, he does seem over-agitated in the moment, and possibly too strict/controlling/micromanaging of his dog (unless he just recently gave the dog a command to stay there before the clip started). But, that's not really strong evidence of a pattern of animal abuse. Neither is having a collar too tight one time.
Some people think shock collars/e-collars are valid training tools. I don't, but it seems strange the media is giving so much attention to a couple of clips showing possible questionable dog training/care practices of a Twitch streamer.
