Also known as robo dogs! They all have different looks and can have antlers or wings, but those are only rare. Legendary is where your robo dog has either a nose on there face or they have a candle tail which they can light when it's dark! Each prodog has a different personality and have different color patterns, but old prodogs have wires hanging out of there joints, but these prodogs live twenty to thirty years at most. Thank you for taking your time and reading this information.
