It is next to impossible to know how many puppies a dog will have in their first litter. Some have small litters and some have large litters there first time, there is no rhyme or reason. If you bred in the right time frame of the heat that optimizes the amount of puppies you will have but you would have to have a timing test done by a Veterinarian. Another way to see how many puppies your dog.
