<human>: I am taking the dog breeder from whom I purchased my dog to small claims court. I'm suing her for the full purchase price of the dog. Here are the facts - 

Purchased the dog at 2 months old
Severe hip dysplasia discovered at 6 months old (condition found by my vet, confirmed by a hip specialist, and confirmed again by a veterinary radiologist in NYC)
The contract I signed with the breeder states that "The puppy is guaranteed for one year from the date of birth under the following conditions: If this puppy is found to have a life threatening hereditary congenital defect or any major health problem or the puppy died, and or suffered from a major congenital disease (cancer, heart disease, or hip dysplasia) that so impaired its life that it would be most humane to euthanize."

Dogs have been held to constitute "goods" within the meaning of section 2-105 of the Uniform Commercial Code, and defendant, a private breeder, is a "merchant" within the meaning of UCC 2-104. Consequently, based on this law the defendant breached the implied warranty of merchantability (UCC 2-314) and should refund the purchase price.

By signing the contract did I lose the right to sue her under the UCC? My dog's hip dysplasia is not so bad that the only thing to do is put it down, but I'm paying through the nose for shots, pills, and specialty food and treats, all to stave off surgery for as long as possible. But my vet says surgery is inevitable.

Summarize the given text in a few sentences.
<bot>: Seeking refund from breeder due to congenital defect in dog. Contract says hip condition must be so bad that only thing to do is euthanize dog. Can I still sue (and win)?
