can the breeder guarantee that the puppy will not have hip or elbow problems?
No breeder can guarantee that your puppy will not have hip or elbow problems. But a responsible breeder will guarantee that if there is a genetic problem with hips and/or elbows, they will replace the puppy or refund your money. Most breeders require the owner to return the puppy for replacement. Do not be dismayed by the breeder requiring the return of the puppy. The puppy may be in a great deal of pain and the owner emotionally unable to deal with having to put the puppy to sleep. A responsible breeder will want what is best for the puppy/dog.
