Happy Gilmore, Below is my hip guarantee. I'm not allowed to post my website w/o being a sponsor, so I copy and pasted it.
The concern that breeders have is the certainty that it really is their pup with the problem.... Here is a scenario. A guy buys a puppy from me and six months later he and his wife decide they want a second pup for company. They buy the same sex and color of pup and all is well until this second pups starts having issues with his hips. He calls the breeder and the breeder says, "Sorry, it's not my problem". So they decide to call me and tell me that their pup they bought from me is having hip problems. My guarantee requires that the buyer gets the pup micro chipped before the pup turns 16 weeks by a licensed vet. The vet must send me a signed statement of the microchip and the microchip #. This allows me to verify that this dog really is one of my pups. I have no problem honoring my guarantee. Fortunately I have never had to, but I will if an issue arises and the buyer simply abides by the guarantee.
No, I don't expect the dog back. I do require it to be spayed, as it's never a good idea to breed a dog that has hip problems. I will replace with a puppy, or money back at my discretion. A good breeder will be very flexible and understanding, but we also have to be aware that there are dishonest people out there and protect ourselves as well. If you buy a pup whose parents have passed their OFA, your dog is very unlikely to have any hip problems.

We guarantee your dogs eyes for the first year. An eye check must be done by a licensed animal eye doctor. This must then be turned into the Canine Eye Registration Foundation. Once the final results are returned and if your dog does not pass due to a non-injury issue, you will be given a puppy replacement, or a refund, at our discretion. The following criteria must be done for this guarantee to be valid:
See above #1-6, and #12-18. If these are not followed, the eye guarantee is void.
