How to Tell a Male From Female Guinea Pig

To tell the difference between a male and female guinea pig, you will need to observe them closely. Here are some key things to look for:

1. Distance between the anus and the genital opening:

- Males: Usually a long distance separating the anus and genital opening.

- Females: Shorter distance between anus and genital opening.

2. Shape of the genital opening:

- Males: The genital opening in male guinea pigs is shaped like a straight line or a small dot.

- Females: The genital opening in female guinea pigs appear Y shaped or a small upside down V.

3. Presence of a penis sheath:

- Males: Male guinea pigs have a small, retractable penis sheath located just below the genital opening.

- Females: Do not have a penis sheath.

4. Behavior and vocalizations:

- Males tend to be more dominant and vocal than females, especially during mating season.

- Females are typically more docile and less vocal.

It is important to note that these are general indicators, and some individual guinea pigs may exhibit variations.

Additionally, it is best to consult with a veterinarian or an experienced guinea pig breeder to confirm the sex of your guinea pig accurately.
