I came up with the following list of possible considerations when you are purchasing or selling a dog with a contract. Fortunately, my breeder did not have me sign such a deal.It depends on the sequence of events, it depends on how you came to find this breeder and what, if anything, the breeder's website says about breeding rights. There are new registration mills, similar to diploma mills. If you wish, include a clause in the contract that allows you to challenge the dog's pet status at a certain point when the dog has matured. Yes. Breeders will often sell puppies on no breeding contracts. Dogs and horses (any equine) are required to be licensed in the City of Los Angeles. License tags identify guardians of lost animals. A statement that the applicant owns the dogs and that there are no other owners. Non-Breeding agreements are a private contract between the seller and the buyer.
