Dogs get their size from a mix of genes from both parents, but it's unpredictable as many genes control size, meaning puppies can be larger, smaller, or in-between the parents, and even littermates vary; while parents offer clues, genetics from grandparents and environment play huge roles. Males often grow larger than females, and nutrition during growth also matters, making it a complex genetic lottery rather than inheriting solely from one side.

Do puppies get size from mom or dad?

A puppy's grownup weight is highly correlated to the parents' weigh. But since you only know one parent, it will be hard to say ahead of time. Female dogs tend to be a bit smaller than male dogs, and correlate closer to their mother's weight. That's a small help in this situation.

Does neutering/spaying affect puppy size?
