Never expect to make money because it will not happen! 1] All puppies should be vet checked a minimum of three times before leaving. 2] All puppies should at least have the first vaccines, mine have one and two done. 3] Puppies should be at least 8 weeks old before leaving no exceptions, mine are 12 weeks. 4] Puppies should be spay or neutered before leaving, or at the very least sold with a contract and the contract should be verified and if not fulfilled then the puppy should be removed. 5] Puppies should be tatooed or microchipped before leaving and registered before leaving. 6] Puppies should come with a guarantee of a minimum of 2 years, mine are 5 years 7] Puppies should be well socialized to children, other pets and daily house hold things 8] Puppies should be well started in their house training, should be crate trained 9] Puppies should be temperment tested and the paperwork should be provided. 10] Puppies should be loved by the breeder and the utmost concern should be given to selling them, many questions should be asked and home visits when ever possible. If that means the breeder hops on a plane to go check the place out then do it, I do. These are just off the top of my head when I think of more I will add htem but other breeders here can add to them too.
