Trouble is there are a lot of assumptions made about labs being easy to train, and in the wrong hands they can be a lot of dog for the misinformed who believe they are all just like guide dogs.
I’m a firm believer with labs that aside from show and working lines there are far more differences. Whenever we’ve had pups and prospective owners come to visit ive always reinforced the fact that whilst lovely dogs, mine is like the F1 version compared to the Volvo/family saloon show/guide dogs....
lovely, she is, obedient, she is, but also highly strung, easily offended and distraught if she gets it wrong, way too intelligent, communicative in ways I had never appreciated was possible before having her, I could go on. I don’t know if this is the field trialling genetics which have changed the breed away from that traditional “easy” image most people have of labs? But they can be far from default in the wrong hands. (Sure I’m preaching to the choir btw.... just my musings)
