Here are some factors that influence litter size:
* The mother's age and health: Younger, healthier dogs tend to have larger litters.
* The breed: Some breeds are known for having larger litters than others.
* The individual dog: Even within the same breed, some dogs will have bigger litters than others.
On average, a Labrador Retriever litter can range from 5 to 10 pups. However, it's not unusual for litters to be smaller or larger than that.
