In the past I've commented on the divide between show and FT lines. I watched/worked British championship field trials. Amazing watching what these dogs were capable of, but they really didn't look like Labs per the breed standard. I've seen "show" Labs with little to no drive to retrieving and I'd say Sophie is a prime example. Good looking dog, but couldn't care less about actually retrieving. Bruce was a very handsome Lab, and had good drive, very eager to please. He's what I would consider a "true" Lab, much like others I've had who would retrieve all day long. Brooks is also a good looking Lab, and he has drive, the kind of drive that once properly harnessed,I think he could work at top levels with the right trainer and training environment, which I can't provide. He is very birdy, will stop and watch a sparrow fly over, and a flock of geese will mesmerize him. Hell, he watches airplanes too.
I've said this before. Labs at their core are the jack of all trades and masters of none. It's the breeders who are breeding them for what THEY want from them that has created this divide. Competitive field trials have evolved into a competition on just how far one can push the envelope. It pits handler against handler and dog against dog. The things these dogs are asked to do are well beyond what the average hunter needs from their dog. Hunt test are more realistic in that the dogs and handlers are confronted with scenarios that they can/would expect in the field. It's the handler and dog against the test.
"Show" breeders breed not necessarily to the standard, but what the judges are putting up as winning dogs. This is an issues affecting many breeds, not just Labs. Go back 20, 30, 40, 50 years and many breeds winners will look nothing like they do today. I've got a copy of the British Labrador Retriever Clubs' 100th anniversary book, which shows the winning dogs at their shows over this time. I can tell you thins, it's an interesting study on the evolution of the "show" side of the breed.
This link is to a speech that Mary Roslin William made at the Kent, Surrey and Sussex Lab Club back in 1986. It's pretty long,and not the greatest recording, but very interesting to say the least. I had the pleasure of meeting her, and conversing with her several times, including a talk she gave at a club back in 1988, which also included Gwen Broadley of Sandylands. If you've got some time to kill, listen to it, it will be time well spent.
