Welcome to the site. Definitely do your research on breeding. You need a very good blood line to breed so you will product very good pups. If your girl is not Champion material, then she should not be bred. Not to say she isn't a beauty. Get a mentor of someone who is a reputable breeder. It is also costly to breed a litter of pups. About $3000.00 to $4000.00 depending on the stud fee and the vet fees.They need to be artificially bred and the pups need to be taken by C-section. There are people out there that do nature whelping, but you are playing Russian Roulette with your pups and bitch. It should not be done. Then after the pups are whelped, you will have about three weeks of no sleep, as you are up every two hours feeding them. It's not as easy as people think and is not for the faint of heart.
