I reccomand that you talk much to her breeder, go few times to see her and how shes doing and check the health in her family
If all the dogs are healthy and in standard and so, then i would first go meet her.
A
good breeder is a breeder that goes outside reguarly with the puppies and lets them walk in grass, mud etc., has the puppies in his home not outside in some kennel, lets them get used to being in a car and takes them for few car rides, who shows his dogs and only breeds from good natured dogs in standard and that has done well in the show ring
A
great breeder is a breeder who does all this and more, who says that if you ever need somebody to give the puppie a haircut he will do it for you for litle money, a breeder who wants to meet the puppie sometimes and who wants news of the puppie in the new home.
A
bad breeder is the one who has the dogs outside in kennels, but not in his own home.
A bad breeder does not go to the vet and let him check them and give them worm medecins etc., a bad breeder dogs just ''are there'' somewhere, even outside in a dirty kennel.
Watch out that your breeder is great !
