Please Help! Found Two Weird Spots On My Guinea Pig's Belly

[Ameliexxx]

Hi! My name is Amelie. First time reaching out for any type of help on the internet lol.
Anywho, I have a young male guinea pig. I've only had him for about a month. About a week and a half after bringing him home, I noticed a brown-ish, red-ish spot on his belly. It looked like it would be sore but he didn't seem to be in any pain. Earlier today, I went to check and see if the spot was still there. Not only is it still there and a lot bigger, but now there is a new small one as well.
His cage is always clean and he's always very happy. He has shown no signs of being in pain or being sick. So I'm really wondering what these two marks could be .. any help is much appreciated - thanks !

Ouch, looks like he might have injured his nipple maybe? I'd double check his sex too, if it's a sow if can mean ovarian problems.

Either way I'd definitely get to a piggy savvy vet to get it checked out. Hope he feels better soon!

Hello and welcome!

To me it looks like the lower one is his nipple and the one in the middle is the mark of his belly button

It looks like a nipple and a belly button to me, which looks like it may have been slightly abraded and has formed a scab; depending on the skin colour, nipples can look different. Check whether the one on the other side feels and looks different in size (the colour will be different anyway) and if there is any swelling underneath that is not symmetrical with the other nipple. If there are noticeable changes in a short time, then you may want to have them vet checked.

The placement looks like one of his nipples and his bellybutton. Pigment changes can take place over time and the nipples can be different colors (I have a pig with one black and one pink nipple.) I would just keep an eye out for any swelling/heat/bleeding that could indicate an injury or infection.

Yep I agree a nipple and the belly button where the umbilical cord was attached.

Lucky guinea pig to have a caring owner who asks questions. Well done.
