As of writing, the most pet robot is the Tombot. The Tombot is created and designed to act, look, and even emote like a real puppy or dog. With that said, the Tombot is seen as a companion and emotional robotic dog rather than a robotic dog toy. This companion pet acts as an emotional support system for seniors, patients, and individuals diagnosed with dementia or Alzheimer’s. Although the Tombot is not yet commercially available, it is already considered one of the best robot dogs by many and one of the most realistic robot dogs to date.
