The International shows are the ones that give written evaluations. Though the UKC judges that I have shown to have been pretty approachable and willing to share what they see in a dog.
UKC also has a pretty cool Juniors Program where kids can start as young as, I think, 3 years old with their parent in the ring with them as they show their dog.
I would highly recommend giving them a try and it is even better if you can go with a friend.
Ethan would LOVE that!
