How many puppies can a retriever give birth to?

Retrievers can have a varying litter size depending on the breed, age, and health of the mother dog. Generally, a retriever can give birth to anywhere from 6 to 12 puppies, although litters of up to 15 have been recorded. Golden Retrievers tend to have larger litter sizes compared to Labrador Retrievers. First-time mothers or older dogs may have smaller litter sizes.
