A great breeder should do both.
Competition is really the only level playing field when comparing abilities across the spectrum. It’s nice that a guy hunts his dogs regularly, but unless you can quantify how that dog performs against other dogs, there’s no benchmark for what is good and what is bad in dog quality.
This is not to say you can’t get a great dog from a backyard breeder who just hunts, I’ve seen it countless times. It’s just a lower probability.
I get that a lot of trainers and handlers get burned out on the politics/showmanship and gameness involved with trials and tests, but unfortunately it’s the best system we have for comparison and competition.
If you were trying to buy the fastest dog, or the prettiest dog, or the fastest horse, would you even consider buying outside of competitive breeders? Ever hear of race horse that wasn’t out horse racing lines?
this is not to say a guy can’t have great dogs that only hunts his dogs, but if I were looking online for dog and didn’t have a chance to spend hours watching the mother and father hunt in the field, I would not be interested in buying a puppy from them. On the other hand, If the dog comes from two National Championship dam/sires, I’m probably going to buy that puppy.
At the end of the day, if you’re buying a pup you can only count on two things: Pedigree or a Personal relationship with the breeding pair. No one who comes on Rokslide looking for dog buying advise has the latter.
