Pup Sexing Pics!
Correctly sexing guinea pigs can be a challenge. And properly sexing pups is the most challenging of all. It helps to be able to examine guinea pigs of both sex to determine the subtle differences.
You may have some difficulty early on figuring out who is who but by 3 weeks of age, sex should be easier to determine. Make sure the male pups are removed from the mother at 3 weeks of age. The tips on the SEXING page may also help.
Paulo has contributed pics of a couple of pups taken at 3 and 5 days of age. Note that both sexes have a pair of nipples. Note that the genitals look very similar. It can be quite difficult to determine the sex of a very young guinea pig. Reread the tips on the sexing page. Here's an early pic of Paulo's surprise pups with their lovely mother:

It is natural to check and recheck your pigs. You want to be absolutely sure you have done it right. Even vets can make mistakes so be sure to double check again as the 3 week cut-off approaches!
