Do Puppies Inherit Their Size More from Mom or Dad?

Discover whether a puppy's size depends more on the mother's or father's genetics and factors influencing their growth.

56 views

The size of a puppy is usually influenced by both the mother and the father's genetics. However, in many cases, the mother's genetics play a slightly more dominant role due to the maternal environment's impact on the development of the fetus. That said, variations exist, and predicting the exact size of a puppy can be challenging without considering the sizes of both parents.
