Hi You cannot really go by Champions etc and show dogs in his ped. Your better if you could go back to who bred him and ask them to evaluate him for you re show quality.
It is harder to start showing with a dog at 3years old, not impossible but harder as they have had no training for the ring.
The dog papers always have show dates and info, but I would ask the breeder of your dog first and try and find any Ringcraft training near you
