Breeding is a serious decision. We should consider improving the breed not just making money. A breeder should always strive for healthier and better quality puppies.
Pet quality dogs should never be used in your breeding program. Their faults will only be passed down to their puppies. Your female should be in excellent health and up to date on all vaccinations. No really small females should be used.
Puppies are a a big responsibility they need to be fed, kept clean and some have medical needs. You should make sure you have the time, dedication and finances that will be necessary before you proceed.
