2 Years Old

• A dog should only be bred after she reaches 2 years of age. A younger dog is not mentally and physically prepared to breed, and forcing her could endanger the dog's health. When a bitch is 5 years old, she should stop breeding because there is a higher risk of complications occurring and infertility could be a problem.
  
  

Not Breeding

• Breeding dogs involves a lot of risk and responsibility, and should only be done to improve the breed. The owner has to spend money and time for vaccinations, X-rays and other tests to determine the dog's suitability for breeding. He also has to provide veterinary care and food for the puppies while searching for new owners.
  
  

Bottom Line

• If you have good reasons to breed your dog and you can commit to the responsibilities that come with breeding, you should only start the process when your dog reaches 2 years of age. At 5 years, a female dog should be spayed and stop reproducing.
