oh Jenny don't listen to that stupid person, other than being incorrect she is also very rude
I agree with Diane, at this stage it is very difficult to judge him. A lot depends on character as well as conformation, boys are a bit "slow" as babies but as soon as those hormones kick in they love to show themselves off, it will also depend on what the judge is looking for and what competition you are up against. As Diane says as long as he doesn't have any obvious conformation faults give it a go and enjoy yourself.
I'm glad you posted this here Jenny - WE are your friends, so get rid of that rude and ignorant person!
Most foals, without any of the obvious 'problems' mentioned by Diane, can be shown and will do well in the ring. There is nothing wrong with De-ago, he's a good looking little fella, so go ahead and have some fun!
