All of the other dogs he trains on video just seem to pick things up immediately
That’s because the whole thing is an illusion videos are edited to make it look like he is training the dogs quickly.
ZG isn’t training the dogs on video, he probably shoots a little bit of the “before” and the initial learning, trained the dog off camera for some period of time and maybe had the people practice with the dogs for a few days or longer, then shot the after “oh look how wonderfully trained!”
It’s not that hard if you let a few days or more pass to let the dog get better, just make sure people are dressed the same and nobody gets a haircut, shaves his beard, or makes another dramatic change, and if you are outside it is a little later in the day or if you are inside that the room looks the same.
Basically what you see is not reality and don’t measure your dog’s progress against ZG videos.
Disclaimer: I don’t know if this is what ZG is doing or not, this is just speculation about how someone could easily make it look like a dog picks up training a lot faster than reality. I’ve never done it, but it doesn’t seem that hard.
