What makes you think the dog doesn’t enjoy it? Perhaps you’re anthropomorphising a bit.

Pets like dogs usually like stuff like this. He’s getting treats and the owners are challenging the dog, which is great. Considering a lot of people that own dogs do nothing with them and don’t stimulate them at all.

i think hes trained to stop from some sort of que, ive seen this before

Yeah the dog simply stops when she moves her hand forward with the reward.

That dog is smarter than some of the people graduating out of high school! LOL!!!

It would be easier to understand if there was sound. Do you know if this video is uploaded to a website where sound is allowed?
