Guinea Pig Skin Issue

[RaisingGuineas]

A few days ago, we noticed this bald patch appear on our guinea’s back. Upon closer look there appears to be dandruff as well. He has no other symptoms or patches like this. Although he does occasionally try to scratch it. What could this be?

It is impossible to tell simply with a photo, but it does look like your boy may have a skin issue.
This could be fungal or also caused by mites and really needs to be seen by a vet.

If you contact your regular vet many will give an initial diagnosis simply with a photo, so no need for a visit.

I would recommend a vet appointment for a proper diagnosis and the correct treatment.
