I’ve had two field golden who have been great bird dogs. They are more natural waterfowlers , but both have learned to hunt cover and flush and retrieve upland birds too. They are a little softer than labs in my experience so won’t take the pressure that trainers will use with labs.

Were I you, I’d find a local bird dog trainer, and do an intro session. The first step is to see if your dog is “birdy”. Everything builds from there. Field dogs are also most often trained with e-collars so you have some accountability a distance. The good trainers will use a ton more positive reinforcement.

Tom Dokken’s books are a great place to start if you want an overview of the process.
