Hyper or High Energy Dogs

Back when I trained Labs, I loved a hyper dog. I wanted them to retrieve the bird going all out and coming back all out. Non of that trotting bs bringing back the bird. They would be wanting to make a retrieve so bad they would be quivering and shaking all over waiting on a command.
When I started with Plotts, the Weems line were much more hyper then the swampland dogs and I have interbred them thru the years. I have had just as many good ones from the hyper line as I have had from the quieter ones. Like the Old Man says the hyper ones take more handling and obedience. That being said, even the quiet ones can cause a ruckus if you dont put a handle on them.
