Surprisingly, the first dog-robots appeared in the distant 1960s. Then they were intended for military purposes, but since the technologies at that time were much worse than they are now, the first experiments with the creation of robot dogs seemed hopeless and these specimens went to museums. The first interactive toys that imitate dogs appeared in the 1990s. Then they were very far from today's models, were able to perform 1-2 commands and give voice. At the same time, they practically did not repeat the movement of the dog.
