Dark Spot

[sooploops]

My female guinea pig has this brown spot on one of her nipples. She has one normal one and one dark one. When we first got her, they were both the same color. After a couple moths passed, I started noticing this brown spot. I’ve taken her to the vet, but they didn’t really check that out. Is it something completely normal or should I be concerned?
The dark spot is the nipple on the right.

Its totally normal, these are the nipples. The darkness on her left one is just the skin colour. My girl is the same

Nothing to worry about. It'd just skin pigmentation that's all.

Thank you for clarifying! I thought it would be something serious.
