Dandruff on guinea pigs is one of the issues they battle with during their lifetime. Perhaps, you have noticed some flaky-like whitish substance on your guinea’s coat, and you are not sure of what to make out of it.

This makes you wonder, what are the causes of dandruff on guinea? How can I treat dandruff on my guinea pig? No worries!

In this blog post, we will discuss in detail the various causes and possible treatments for dandruff on guinea pigs.


Dandruff is a skin issue whereby the outer layer of the skin is shredded more often than normal.

Since Guinea pigs are rodents with a lot of hairs on them, they are prone to dandruff disease. Dandruff flourishes well in dry skin, so if a Guinea lives in an area of low humidity then it’s easy to contact dandruff.


Although dandruff is invisible, there are a few ways to dictate them on your Guinea pigs. This knowledge helps you take better care of your guinea, and dictate if it has dandruff disease.

  • Excessive Scratching
  • Pains and irritation once you touch your Guinea Cramp


1. Dry Skin

This is among the most common causes of dandruff in Guinea pigs. As earlier mentioned, dandruff-causing bacteria thrive well in dry skin.

Therefore, if your guinea’s body is dry then it has a high chance of contracting dandruff.

2. Low Nutrient Level

Lack of enough nutrients or poor diet can cause dandruff in Guinea pigs. That’s not all. It can also lead to several health challenges.

For instance, a lack of enough calcium in a guinea’s food can lead to overgrown teeth and other tooth issues.

To avoid this occurrence, always feed your Guinea with a balanced diet. In other words, their food should include hay, vegetables, pellets, and fruits.

Feeding them with treats, snacks or sugary items is unhealthy. If continued, this might lead to excessive weight gain and other health problems.

3. Excessive Moisture

When your guinea’s cage is overly dirty and wet, it makes way for bacteria and parasites to inhabit. Before long, this will likely lead to dandruff infection.

If your Guinea has been living in a dirty or wet cage for a long time, you could start by tackling the issue from the root. In other words, keep their cage clean and dry at all times.

4. Lack of Vitamin C

Vitamin C is an essential nutrient in a guinea’s diet as it serves as a cofactor in the release of tissues and enzymes in the body like Collagen. Guinea pigs require about 10-50kg of Vit C to maintain a healthy diet.

Asides from pellets, Guinea pigs can also feed on fresh vegetables, broccoli, spinach, and leafy greens for Vit C.

5. External Parasites

Certain parasites could also be responsible for dandruff in Guinea pigs. A study on parasites like mites, fleas, and lice shows they are prone to cause skin infections in both humans and animals.

As a Guinea owner, it’s easier to notice whether or not your Guinea is battling with fungal infection. It develops a wet coat and may start scratching various parts of the body more than normal.

The next step would be to get it tested with anti-fungal medicine.

6. Unhygienic Habitat

As important as it is to live in a clean environment as humans, your pets should do the same. A dirty, crowded cage for your Guinea is a clear invitation for bacterial infections.

Subsequently, your Guinea develops an overgrowth of bacteria which leads to dandruff. Guinea’s best suited to clean, healthy environments.

If possible, you can develop a routine where you clean and bathe your Guinea every week.
