My head canon is that he's a severely autistic teenager with billionaire tech parents that develop AI-based autonomous robotic helpers. They gave him a bunch (mostly dog shaped) and a literal warehouse built to be Adventure Bay, so he lives out his days happy and "helping people" with his pups. In reality he's beta testing his parents' prototypes with edge cases no regular user could even think to come up with. The show is what Ryder thinks is happening, but it's 50% in his head, and 50% enabled by his parents' products. He is a more closely guarded secret than all of their IP combined. He doesn't exist as far as anyone knows.

We don't speak of how many pups get destroyed, or what fluids may get into them.

they fell out of lighthouses. separate incidents.

I’d love to have, like, 1/10 of Ryder’s annual budget.

I have a theory about Ryder. I think he is secretly Bruce Wayne, Ryder is his codename. Hence, he has the funds to build extreme HQs, train some awesome dogs, and teach them how to drive vehicles. This also covers why his parents are not around as they were murdered. I am waiting for the series to end after one of the pups dies on duty, and he realizes he can only rely on himself to keep everyone safe.
