Identifying Skin Problems

Fungal Infections vs Parasitic Infestations

Here are some pointers to help you to decide if your guinea has a fungal or parasitic skin problem. Once you have figured out which one it is, please visit our Recommendations page for more information about how you can help your guinea's skin.  Also visit our photo gallery and see what some of the most common skin problems look like.

Typical Symptoms Of Fungal Infections
Typical Symptoms Of Mange Mite Infestation

Hair falls out with a light tug, and the end of the hair will be coated with scurf / dead skin. There is often a white bloom to the skin.

Thinning hair with bald areas only in the area of infestation, often with an inverted V-shape in the middle of the back.

Heavy, gritty scurf (like dandruff).  There may be white tide marks on the ears and / or jagged edges.

Hair shafts broken off half way down to the root around the area of infestation.

Very greasy hair and / or skin that is red (rather than a healthy pink colour). Often feels hot to the touch.

Hair will not come out when lightly tugged.

Intense scratching, biting and irate squeaking. Nerves are often affected and if you touch them around the hip area they will often turn round and try and bite you.

A little bump / scab on the skin surface - this is the tiny mite just below the skin. Sometimes you will see spots of dried blood caused when the mite is burrowing under the skin.

If the infection is bad, there may be thick crusty patches of skin, extensive hair loss, considerable scratch lesions, and the guinea may even be fitting.

Intense scratching / irritation which may lead to fitting if left untreated.
