[blueskies]

Not going to comment on the breeder or what one should or shouldn't cover or offer, but I did want to point this out: the OP obviously read and signed the contract when he/she purchased the puppy in the first place. If you did not agree with the contract in the first place, why did you sign it? Why didn't you just find another breeder? The fact is, you did sign that contract, and that is not the breeders fault. The blame does not all go on one person here, it is both parties. The OP should have researched and found a breeder and contract that he/she was comfortable with. The fact is, you are bound by that contract because you signed it. Not saying it's fair or not fair, but it is what it is.

Also, the poster above is correct, just because parents don't have it does not mean it's not in the lines, and sometimes there is no way to tell. Health issues will, at one point or another, come up in a breeder's program. Unfortunately Yorkies are a breed that carry many genetic health problems in their lines. Even a line that has been clear for many years can have something come up randomly. However, I do believe that those two parents should never be bred together again, and if either parent bred to another dog has the health issue come up again, then they should be spayed/neutered and all puppies from those litters as well.

Again, not trying to point fingers here, just playing Devil's Advocate.
