What determines how many puppies a female dog has?
Usually, the size of a dog litter is mainly based on the dog’s body size — simply because biologically, bigger bodies are able to carry a larger litter size than smaller bodies. The litter size also depends on the breed of the female. Some small dog breeds will only bear one puppy at a time; we call these singletons.
