This is simple, it's because a dog is ALIVE and a robot dog is NOT.
one is alive one is dead
Robot dogs are great, but anteater robots work on the same mechanism and should be great, too.

There are different parts of a robot
There are several films, movies which have a giant robot. Some of them are Robot and Frank, Wall E, and many other different cartoons which feature a giant robot.
Every robot has a different function, but overall, robots are designed to have a positive impact on humanity.
Considerably less than an actual dog. Plus, robot dogs aren't loyal and do not love you, so I wouldn't recommend one.
They are functionally identical.
A robot can't save the earth. A robot could help people around the world in different ways but it can't save the world! Only god can do that! :)
Robot sensors detect different things and send different amounts of electricity to the Robot's controller board to tell their findings. Then the controller board uses these different amounts of electricity to interact with its surroundings. Example: Lets say you have a robot that is made to follow light. Lets say your robot has 3 light sensors. One in the front of your robot one on the right and one on the left side. The sensors will detect how much light is on the front, right, and left sides and send this data to the controller board. Then the controller board uses this data to tell the robot with direction to go.
