Are there really any differences between male & female puppies?

Good question — the truth is:

As puppies, there are very few natural differences between males and females.

Most of the noticeable differences people talk about (like marking, humping, heat cycles, or clinginess) usually don’t show up until adolescence or sexual maturity (around 6–12 months old).

Here’s how it breaks down:

As Puppies (under 6 months):

• Males and females usually behave the same — playful, curious, and energetic.

• Training ability, friendliness, and confidence come more from individual temperament and early socialisation than gender.

• Size differences between males and females of the same litter are usually small at this stage.

As They Mature:

• Males may become more territorial (marking, humping).

• Females may go into heat if not spayed, which brings mood changes and attracts male dogs.

• Some breeds show stronger sex-linked tendencies (e.g., male Golden Retrievers often being more goofy/affectionate, females more focused).

  
  
  
  
  

  Bottom line: For young puppies, the difference is minimal. Personality, breed, and training shape them far more than gender.
