Male Guinea Pig Overview

Personality Character

Male guinea pigs are generally friendlier and more confident. They also tend to behave better when a part of a smaller group that consists of two or three male guinea pigs. Male pigs are more responsive and more inquisitive than female guinea pigs.

Boars are also more likely to take an interest in exploring their surroundings. There is a misconception that male guinea pigs possess an aggressive disposition. However, there is little evidence to support this claim.

Health and Caring

Male guinea pigs are more likely to deal with health conditions such as impaction as they get older. This is the build-up of fecal material in a guinea pig’s anal sack. As muscles weaken, it is difficult for these males to adequately empty their bowels when passing fecal matter through their digestive system.

As a result, the care provided to these guinea pigs is also tailored according to their health. However, impaction is often a manageable condition for caretakers of male guinea pigs to deal with.

Female Guinea Pig Overview

Personality Character

When observed alone and in a large group with fellow sows, female guinea pigs display an interesting set of social dynamics. They are more comfortable existing among their kind in large groups.

While female guinea pigs are generally seen as being shyer and more reserved, they are also more likely to “bicker” and argue with one another to assert their social standing in a group. This proves to be quite an interesting personality trait in humans and animals alike.

Sows are initially reluctant to let their owners carry them, but in due time they grow comfortable and can develop bonds with owners that are similar to their male counterparts.

Once comfortable, sows will seek protection and support from their owners when they are afraid. Sows will also provide a calming effect on fellow females when they are experiencing stressful feelings.

Health and Care

Female guinea pigs require an exorbitant amount of timothy hay from their owners and a plentiful supply of fruits and vegetables. They are also neater and tend to create less mess in their area. Female guinea pigs require occasional baths and nail clipping sessions to maintain their hygiene.

Once settled, the female guinea pig generally requires less care compared to the male and thus proves to be less high maintenance to care for.

How To Tell the Difference Between a Female and male Guinea Pig?


There are a few metrics by which one can differentiate between a male and a female guinea pig. On average, there is not a significant difference between the size of female and male guinea pigs.

When they reach middle age, they grow to be roughly the same size. Male guinea pigs weigh a bit more than their female counterparts and weigh about 0.5 pounds more than females.


The typical lifespan of both female and male guinea pigs is generally four to eight years. With age and varying health issues, this lifespan is sometimes shortened.


In terms of smell, male guinea pigs tend to have a stronger and more pungent smell when compared to female guinea pigs. This is because they secrete a trail from their grease gland when they choose to show domination and want to mark their area with a reminder that they were present there before any other male guinea.

The area around this gland is where the guinea pig’s tail is located and can hence begin to smell if not taken care of properly.


Female guinea pigs exhibit a greater degree of cleanliness, a stereotype that also holds for humans when comparing females to males in the human world. They throw less food on the floor, keep their surroundings neat, and are more concerned with the degree of cleanliness present in their living space.

Conversely, males tend to be messier and less concerned with keeping their living space neat and tidy.


In terms of personality, as stated earlier, male boars tend to be friendlier and easier to a pet than female guinea pigs. However, the amount of care and attention given to a guinea pig by its pet owners plays a significant role in the personality of a guinea pig eventually develops.

Guinea’s that have been cared for and paid attention to tend to have more trust in humans, and as a result, they are likely to be more playful and agreeable.


While male guinea pigs are associated with aggression, they tend to be gentle and caring in nature. However, male guinea pigs that have been mistreated by owners or in shelters develop aggressive qualities to protect themselves. Female guinea pigs are more reserved, shy, and subdued. However, male guinea pigs can demonstrate loving and friendly personality traits with time and give love and patience.


A male guinea pig is noisier due to the brief sounds, compared to a chirp or the sound that guns make when bullets are put into place, and a “click” sound is heard.

Sexing guinea pigs refers to determining the sex of a guinea pig according to the reproductive organs they possess. The most convenient way to do this is to place the guinea pig on its back or bottom and place a cloth on their backs so that they are cradled and, more importantly, comfortable.

Once you decide to adopt a guinea pig, it is best to take the due time required to truly understand the needs and nature of the being you are planning to own, nurture and care for.

Guinea pigs can display extremely friendly, caring, and lovable characteristics and can cure an owner of feelings of loneliness, sadness, and the general human condition of feeling useless if there is not someone or something available to care for and provide for.
