Generally, the average litter size is between 4-6 puppies.
However, some breeds are known for having larger litters, such as:
* Great Danes: Can have litters of 8-12 puppies
* Labrador Retrievers: Can have litters of 6-10 puppies
* Golden Retrievers: Can have litters of 6-9 puppies
Smaller breeds tend to have smaller litters, with some breeds only having 1-3 puppies per litter.
It's important to note that these are just averages and the actual size of a litter can vary significantly. Factors like the age and health of the mother dog, genetics, and environmental factors can all influence litter size.
