I think LAbguy is on to something here.
I hunt with a field trial bred lab, who is used as a hunting dog and she is a PITA in the blind. She is a fabulous retriever but she never calms down. In the house, blind or truck. Her owner loves that about her...Me? She's fun to run at a test but then I am soooooooo glad she doesn't live with me.
I watched a number of dogs this weekend at a simple WC/ I/ X test that I would not take into a blind with me because they were off the wall wired for sound.
For the average person it's going to take a whole lot of education, time and effort to bring out the best in these dogs. Good luck.
If I was in the market for a Hunt Test/ hunting lab (blahh-blahh-spit-yuck ) I'd look at Cedar Brae.
If I wanted to do Field Trials / hunting I'd look at FT lines.
And if I bought a lab from FT lines I know I'd have to do some serious training to end up with a dog that I could live with that is not a PITA.
