The first dog I purchased is a four year old pleasure dog. She is perfect for his introduction. We have taken her to two pleasure trials and she has performed very well but not placed. My son handles her well so I ask no more from her.
I then purchased a puppy of 4 months. He was pointing and backing at this age. We carried him to a fun trial just to more or less watch but I let my son run him in the puppy brace. He did OK for the competion and great for his age. They needed a dog to fill the last brace in the derby. I entered the pup and my son and they placed third out of six dogs. I was overjoyed.

I know this has been long but I wanted you to have the background before the question. The pup is now 11 months old and at the trainers. He is holding to flush and retrieving naturally. The trainer has said that he would like to try the pup this fall on the field trial circuit. Is it better to let the trainer handle the dog or let my son try it with no experience? I want my son to enjoy experiences but don't want to waste the dog. I know that my son and I can accompany the trainer for the experience. What would be ideal?
