They're amazingly aggressive on that supplement crap. The web design is pretty poor, with giant type and red type being a bit overused, especially in the context of the supplements-- it comes across as a loud, obnoxious used-car sales pitch. But that's just kind of a peeve of mine.
Of course it would be nice to know what genetic disorders have been screened & what health tests were done, moreso than how awesome the supplements are...
One thing that would be nice in the breed organizations in general would be health & longevity certifications to distinguish sires & dams that had such traits, if it were realistically possible to do so, though the longevity milestone would be rolling around after most animals' breeding careers are over. I'd think it's safe to say that over 80% of the Doberpeople around the world don't care about things like show awards & ScH titles-- they want dogs that conform to the breed standard, who are just generally healthy. Yes, it's definitely important to preserve the standard by selective breeding, but health often seems to be the cost with selective breeding programs that have a different primary focus, and the folks in charge of those programs may not know there's an impending disaster until it's too late. Or, they might just always be flirting with disaster, pushing the limits a bit too close, as is typically the case with the desire for the way legs are set in the rack posture for showing always seeming to be right on the edge of a propensity for hip dysplasia.
The million dollar question is whether the non-focused breeding programs (hobby, BYB) who breed non-distinguished stock, but who have enthusiasm for their dogs like these "Sureshot" folks, have a better chance of breeding for health & longevity traits. Whether it's deliberate or through the slight edge that the genetic diversity of not-thoroughly-thought-through pairings might have, it seems like there might be good odds, just so long as it's not completely haphazard breeding from substandard stock. For example, might a bitch with lots of ancestors with working titles in her pedigree, bred to a dog with show titles in his pedigree, have a better chance of producing offspring that may be mediocre at either activity, but might be superb generalists with better overall health?
I guess the primary conclusion I would reach is that these folks are emphasizing their Dobes' pet lifestyles & temperaments. It appears that their dogs (and the puppies they are selling) are spoiled rotten. That's way better than a puppy mill, but maybe not the best puppy source if one has any remote desire to engage in competitive activities down the road and health & longevity might be pretty hit-or-miss if they don't have the genetic tests & other documentation on their breeding stock.
