Hi,
I would start with asking the simple things how long have they had the breed etc. How many litters they breed per year/have bred per year. Normally the better breeders only breed when they actually want a pup for themselves, this tends to ensure breeders are not just breeding litter after litter for financial reasons.
Ask to see the planned mother of the pups and all the breeders other dogs. Where they sleep etc. just common sense things really, do they look happy and healthy!
Then move on to asking about the stud dog, if possible it would be nice to be able to go and see the stud dog as well but this isn't always possible.
Ask to see copies of health certificates.
Getting in touch if people who have had pups from the breeder is sometimes helpful.
Also ask about the puppy contract and puppy pack you would get. Should detail pedigree, insurance, copies of health certificates for mother and father of pups plus most importantly what would happen if for any reason you cannot look after the pup at any point in its life. Good breeders will always take it back.
Be prepared though you should be expected to be grilled by the breeder as well to see if you are suitable. Breeders may not give you all the information at once until they feel happy with you!
I would speak to breeders, then arrange to visit long before the pups are planned.
Finally ask when you will be allowed to visit the ours once born, it should be at least 2 or 3 times before you then bring the pup home.
Hope that helps.
I think the KC do have info on their website as to the type of questions you should be asking.
The breed is known for health problems so by doing your homework you can minimise any problems. Just remember to let your head rule your heart, your heart can kick in when you bring a lovely puppy into your home!
Good luck, always an exciting time!
