Regulations state that papers MUST NOT be offered for sale as an additional charge on top of the purchase price of the puppies. Breeders can choose to place Non-Breeding agreements on puppies sold, if the quality of the puppy is not of high enough standard to warrant breeding with. Breeder's agreements can also be entered into, but the papers must still be transferred into the new owner's name, or into the joint names of the new owner and the breeder. It is your right to legally own any dog in your care. Nobody can guarantee the future health of a puppy, but an agreement about appropriate courses of action should there be a problem in the future can be made.
Verbal agreements are very hard to enforce, so seek a written agreement from a responsible breeder.
Of course the breeder will expect that you play your part as well. You must observe for yourself - the conditions that the dogs are kept in at the breeder's establishment. Belgians in kennels are not living up to their fullest potential, and puppies raised in this environment are getting an unfairly disadvantaged start to life, compared with puppies that are raised in a family household environment. To be well adjusted adults, puppies require exposure to sights and sounds that just aren't present in a kennel situation. You must observe for yourself - the temperament of the parents of the litter .
