Robotic dogs are robots built to resemble dogs in appearance and behavior. Most robotic dogs can bark and wag their tail.

The most expensive, and realistic, robotic dog is Sony's Aibo. Being able to walk and see its environment via camera, and recognize spoken commands, the AIBO robotic dog is an autonomous robot. Aibo is able to learn and mature based on external stimuli from their owner or environment. The Life AIBOware allows the robot to be raised from pup to fully grown adult while going through various stages of development as its owner interacts with it.

On January 26, 2006 Sony announced that it would discontinue AIBO and several other products as of March, 2006. AIBO will still be supported until 2013 (ERS7 model), however, and AIBO technology will continue to be developed for use in other consumer products.

The Robopet is a robotic dog produced by WowWee that is based on the work of Mark W. Tilden. The Robopet has IR, audio and tilt sensors and is able to walk around autonomously detecting and reacting to objects and sounds. It also performs dog tricks like howling, begging, rolling over, and playing dead.

A less life-like dog than the Robopet, is the iDog. Unlike the Robopet from WowWee, the iDog does not have autonomously behavior. The iDog is more of an entertainment device for younger children and can react to music from an external source, such as an MP3 player. It can dance to the beat of the music.
