many breeders supply a contract for any relocated dog for the sole purpose of safeguarding his health and welfare. i believe that a signed contract may suggest and motivate an added layer of accepted responsibility by the seller and the buyer and is, therefore, a protection for the dog, the new owner, and the breeder. the akc does suggest that agreements between individuals should be in writing that clearly states all obligations and circumstances and that all parties should receive a copy of the agreement. it should be obvious that the overall intent is the protection of the dog. the buyer shall keep the dog as a household pet.
