Bald spots on your guinea pig could be caused by mange mites, fungal infections, or metabolic hair loss. Metabolic hair loss could be because of a vitamin d deficiency, a bacterial infection (Cryptococcosis or staphylococcal dermatitis), or low protein diet. Balding can be common for guinea pigs near weaning age or for those who are post partum.
I do not think a guinea pig would lose hair due to stress. There is usually an underlying medical reason if they are licking or chewing. Seek medical attention. add a comment
