Hi! My name is Katie :D

Im not sure if I can edit the post but I meant to say that I am hoping I am just overthinking it. I do not want anything to be wrong with her!

A bald spot on the nose is usually fungus, and is easily treated. See https://www.guinealynx.info/fungus.html. Get one of the creams mentioned (I prefer Lotrimin or Nystatin to Monistat), and apply sparingly with a q-tip. Wash your hands well afterward, since most fungi can travel from species to species, but not too easily. Keep applying even after the hair starts to grow back, as fungus can be stubborn to get rid of.

If you got them a pet store, take them out, turn them over, and compare their private parts to make sure you have two females. Pet stores are notorious for selling sick, missexed pigs with parasites, and with the baby sows pregnant.

If you're a new guinea pig owner, here's some reading material:

Thank you so much! That is wonderful information!!! Yes, I am a new guinea pig and already checked myself to make sure they are females (do not want to wake up to a surprise one day) but I will always need more information even if I did months in advance of research about them. Once again thank you

Also one more question. I got both the girls together and was wondering if it is to late to quarantine them? Meeka isn't showing any hair loss, patches, or itching. So what would be the best for this situation?

If they've been together, there's no point in quarantine -- each has already been thoroughly exposed to the other one.

Quarantine is recommended when you're bringing a new pig into your home and you've already got pigs. That keeps the new one from sharing diseases/pests with the ones you've got. But even then, if you get a pig from a reliable source and you trust that it isn't ill or infested, you can skip quarantine. It's also often skipped for baby pigs that have just been separated from their moms -- they wheek really pitifully, and not many people are hard hearted enough to make them stay by themselves if there's another pig around to put them with.

I usually only separate pigs if one has a serious illness that's really contagious, which means I almost never separate them. I figure by the time I know something is wrong with one of them, the others have already been exposed.

Alright thank you

Just wanted to give a update on Mia's nose. It is officially all gone and she is a very happy guinea pig. Thank you again for helping us out

Oh my gosh that face. What a cutie!

Awww thanks!

Hehe!! What a cutie she is, glad she's all better
