If you can find a fun gundog class he would probably love it
I have tried both with Coco (to a very low standard
) and she has loved both and she and I have both gained
They are both training that will require Brody to use his brain so I would do either - depends what you can find locally and what you fancy doing yourself
As Helen says, he may not be too popular in a proper gundog class - I have a similar problem, Coco gets so excited she barked her head off in class until it was her turn to do her thing
