Smoky73, at age six you would not be (morally or contractually) entitled to money back for your Corgi's hip dysplasia.
Dysplasia is a developmental disease of genetic origin. In English, that means that a dog can inherit more or less of a genetic propensity to dysplastic hips, but the degree to which the dog will be clinically affected is highly determined by nutrition, exercise, weight, general management practices, and traumatic injury. (If an injury is severe enough, one really cannot assess a dog's hips -- this often happens when dogs are hit by cars.)
Most ethical breeders' contracts require that the pup be radiographed and assessed for dysplasia by 24 months (or earlier). If you don't do the diagnostics early in life and get the information back to the breeder for his or her quality-assurance program, you can't expect to get a refund on a middle-aged dog that is now showing radiographic or clinical signs.
Pups cannot be assessed at all prior to 4 months of age, and the preliminary radiographs taken at that time will only definitively detect the most severe cases. I don't put any credence in prelims until the pup is at least 12 months old, whether they are assessed by OFA or the more involved and expensive PennHIP process -- even though PennHIP claims to be predictive much earlier.
I take it that your Corgi's breeder did not check hips on her breeding stock, which is minimal due diligence, but still no "guarantee" -- one can breed two dogs with great hips on radiograph, great structure and movement, and still get a dysplastic pup. Again, you are just stacking the odds. There are no certainties in animal breeding. Dysplasia is polygenic, not a simple recessive or dominant thing.
I'd encourage you, though, to get a second opinion on your Corgi's need for surgical intervention, especially given her age.
A lean, well-muscled dog who has regular moderate exercise often does much better with anti-inflammatories and nutraceuticals (I recommend glycoflex, but there are many good products nowadays) than with surgery.
My first search and rescue partner radiographed moderately dysplastic at 24 months of age. Well, Lilly was already an operational SAR dog, and had no clinical signs at that time. With daily moderate exercise, regular work, glycoflex, and the power of her own enormous heart, she worked until after her 11th birthday -- a very long career for any German shepherd. She died at 13 1/2, of cancer, still able to get around pretty well. (And FWIW, Lilly came from a German working line -- ALL of her ancestors had healthy hips for many generations.)
