Newborn Pups- Help with Sexing

[perfectpiggies]

Hello! I am new here, and I want to get into using this forum more often. But I am getting a 3rd guinea pig, and someone's guinea pig just gave birth and they need to rehome them, so I offered to take one in. But the only problem is, the two I already have are female, so I would need another female. Right now, as of Sunday, August 21st, they are about 3 days old, and I would like to see if you could tell just yet if they are female or male. Tell me what you think, I need help! (PS, they will be with their mom for about 3 more weeks, so I will post another picture in a week or two to confirm which is which gender. Thanks!)

Ok, thank you so much! That is what I thought. I will be posting another set of pictures in about a week or two to confirm. Thanks again! xx
