Assuming that proper health testing takes place... those are some of the nicest, most balanced Labs I've seen!
When I saw "UK Labs" I was thinking of the standard overweight Rottie-looking Labs I'm used to seeing when I hear "English Labrador".
The mill like vibe isn't my favorite, but I'm also never going to get a Lab, so I'm not that bothered by it. Considering the fact that Labs are (by TWICE as many registered dogs as the second most popular breed) insanely popular family dogs, it's awesome that a breeding program is producing athletic, sound working dogs who are also calm and family friendly. And they're beautiful! Field Labs tend to lack in the looks department, lots of snipy noses and badly put together. I don't know if it's just in my area, but I see so many Labs with barrel bodies and skinny legs, just unbalanced but that's "ok" because they're "working dogs". I meet a lot of field Labs who are perfectly nice working dogs but who are wayyyy too hyper & way too much dog for the family that innocently bought them as a puppy... not that I prefer that to giant, out of standard Labs who couldn't perform the job that the breed is intended for. I'd much rather this breeder producing lots of quality dogs than a bunch of BYB's producing physically/temperamentally unsound, out of standard, neurotically hyper or shockingly sedate Labs. There is a huge demand for the breed and this breeder seems excellent. The fact that they produce hunting dogs AND service dogs from the same stock is amazing.
