Our pup Floyd was diagnosed with Hypercuricoseria shortly after we got him. This is a hereditary. His genetic testing showed he had both mutated genes meaning both mom and dad had to be carrIers. I kept our breeder in the loop during all the testing. When the results came out we were offered to give him back and get a new puppy or our money back. Of course we could do neither as we already loved him. I was very disappointed to see a month later he was breeding the same dog. Unfortunately I think we are given this health guarantee and if something goes wrong we are offered a new puppy which most of us would not consider taking and they know that........makes me sad.
