Robotic pets have been a vision of the future for longer than you can probably guess. But most iterations have been pretty disappointing, to say the least.

This robotic “guard dog,” was released by Japan’s Sanyo Electric and was supposed to cost about $750 U.S. at the time, or roughly $1,200 adjusted for inflation. But this dog, just like the robotic pets of the 2020s, aren’t putting flesh-and-blood pooches out of work anytime soon.
