could anyone please give me a rough outline of how to draw up a puppy contract? it is the endorsements i am thinking of as without a signed contract i believe they are worthless? thanks

This is what mine says about it:

This puppy's registration is endorsed not for breeding and not for export. The breeder will arrange for the breeding endorsement to be lifted at a suitable date should the new owner wish to breed, provided that the dog has been hip scored within the breed's normal range, has been eye tested clear, is of sound temperament and general health with no major conformation faults according to the KC breed standard, and that any potential plans for breeding is discussed with the breeder in advance.

I just put in a statement that the puppy has its registration endorsed with the following endorsements .... and list them, and get the buyer to sign to say that they are aware of the endorsements.  I make no mention of lifting them in my contracts any more.
