I'd also add the necessity to sign a detailed contract indicating clearly the obligations and duties of the breeder and owner in order to protect the puppy legally.The contract should also include the contingency plan + details about additional expences if something went wrong. Even if it turned hard or impossible to make the breeder or owner fulfil the agreed obligations, at least it would be clear who and where failed.
Why not put on wolfdog.org sample agreements/contracts suitable for various countries prepared by local breeders? Should a breeder want to send a pup to a specific country, he would have great help. Local breeders could anticipate situations of which the breeder wouldn't even think of
