We do contracts for all of our puppies, but it has nothing to do with breeding rights, etc. The contract states the expectations we have for the buyer, as well as what they can expect from us/our puppies. It's just the general care and maintenance and 'regular' information. However, we have a bulldog breeder here in town who does the same thing you are talking about. Her bulldogs are not show dogs but there are champion bloodlines in her breeding stock. She will not provide papers to you unless you sign a spay/neuter contract and bring her proof of the spay/neuter having taken place. She also does the 'puppy back' scenario. I understand, to a point, where she's coming from because she doesn't want her 'line' being 'contaminated' because she says she has worked for approx. 20 years to get her own line going. What I do have a problem with is selling puppies for such a high price and promising (signing a contract) that they will not be used for breeding purposes...this is especially true when the the puppy does not even have show quality potential. This is a tough situation, as is the thought of unintentionally selling a puppy that will grow up to be bred to death; that is what scares me. We ended up with a solid white female with our recent litter of 3. I am scared to sell her without a spay/neuter contract. We, so far, have decided that we're going to keep her to avoid this situation all together. However, we can't keep a puppy from every litter ;-)
$2000 sounds about right for our area, too. That goes for AKC, NKC and CKC alike. Sometimes they're more or less, depending on the lines.
