Hi, my friend has recently bought two guinea ("male") pigs that were wrongly sexed and actually were female and male, so yeah they mated, and now they are stuck with 3 cute but cheeky guinea pig babies that they don't want to sell. Is it possible to neuter the daddy even though it's already mated to prevent further pregnancies?
Thx xx ( P.s: The three babies were all female, we took them to the vet to check over so they are all healthy :3 )
Hi and welcome
Yes, dad can be neutered at any stage. Neutering only removed the ability to make babies, it doesn't change boar behaviour. My own neutered boars (one of them is a neglect case ex-breeding boar) still mate with their sows when they come into season and show the whole normal social behaviour.
We have got several members with neutered dads or sons now having joined mum and any female offspring.
However, you need to preferably find either a general vet with plenty of practice in guinea pig neutering or an exotics vets with experience in small furries operations in order to minimise the still rather high risk of post-op complications.
You also need to factor in a full 6 weeks post-op wait until a boar 100% safe to go with sows. The little baby in my avatar is the unplanned daughter of a supposedly safe over 5 weeks post-op boar (not one of mine); just to prove the point that is can really happen as late as that and that it is well worth waiting in order to prevent every chance of another pregnancy with mum and any daughters. Dad can live alongside his ladies with interaction through the bars, just as long as he cannot get into their pen.
Your friend is welcome to join our forum for ongoing support and if she wants a second opinion on the sex of her babies; in my experience, it is always best to get more than one.
