Google's robotic dog Spot has a new playmate—an actual dog.

The team behind Spot recently introduced the robot to Alex, an adorable real-life terrier reportedly owned by Android co-founder Andy Rubin, who previously managed Google's robotics division for about a year. As you can see from the YouTube video, posted Sunday by Steve Jurvetson, a partner at venture capitalist firm DFJ, the two canines didn't exactly get along.

Alex basically runs circles around the robot, barking incessantly. After witnessing the spectacle in person, Jurvetson told IEEE Spectrum he was impressed by Spot's "lifelike movement."

"The tradition of the uncanny valley continues...to the un-canine valley!" he quipped.

A second new video of Spot posted by Jurvetson shows the robot wake up from a reclined position, stand up, and take a little romp around a parking lot. Spot is capable of standing up tall on its legs, crouching down, sitting, moving its metal torso side to side, and climbing up and down curbs. It also has a few different gaits, ranging from a slow walk to a faster trot.

First unveiled in February 2015, Spot was developed by Boston Dynamics, the now Google-owned company behind an army of super-strong, animal- and human-like robots with names like BigDog, Cheetah, WildCat, and Atlas. Though Spot is the smallest of the posse, it still weighs in at a hefty 160 pounds.

Unlike Boston Dymanics's other robots, Spot was designed to work indoors as well as outside, the company has said. It's electrically powered and hydraulically actuated, and has a so-called "sensor head" that helps it navigate through rough terrain.
