My Female Guinea Pig Won't Breed. Help!!?

Question

I recently bought two male guinea pigs from the pet store. They are definitely both males and are ready for breeding so I decided to try to breed my 6 month old female guinea pig to one of them. I put them outside in a pen at first both males and the female but every time one of the males tried to mount her she would twist around quickly and bite him and then run away. I tried putting one male alone in her cage at different times but she still would not breed. She would do the same thing, twisting around, biting the male, and then running away. Do you think there is anything wrong with her? I have tried for a little over a month right now and she refuses to breed. What is a sure way I can tell she is in heat?

Oh I forgot to include that I put her in the males cage with both males in their and that I supervised all of the meetings.

The other poster is right, some pigs just aren't breeders. I've got a GORGEOUS female that i've been trying to breed since she was of age and she just won't have it. I actually have housed her with the male for about a month and a half, two months now, and nothing has happened. He loves her, constantly tries to mount her to no avail. She runs and screams like he's trying to kill her (maybe she was abused in the past LOL). A real shame cause she's a beauty but it isn't meant to happen. My calico guinea pig was a perfect one. She got pregnant as soon as I put them together. Like within a couple weeks I could tell she was different and what do you know, three beautiful babies were born and shes perfectly healthy now. So I would just keep trying. You don't have to supervise, and it may help to give them personal time as they can be skittish with people around. No one is going to get hurt. Even the most aggressive males won't harm a female, just other males. I've got a stud pig who is a real ladies man..will mount any female if given the chance, but will terrorize any male he is placed with and has to be put in a separate cage at night (so I can actually get some sleep. LOL)

Female guinea pigs go into heat about once every 2 weeks. If she hasn't let them impregnate her yet, she's not about to start. Plus, if she feels dominant over them (which is a function of personality), she is not about to let them mount her (which would be a sign of her submission). This is doubly so if you have them in a small (less than 15 sq. foot) cage.

Have you checked her for mites? If she has any, any sort of touching can be painful for her. She won't let the males mount her, in this case, and she'll be quick to bite them for even trying. Plus, if she had mites, there's a very, very high probability that the males have them now too...that's 3 rounds of ivemectin and individual isolation for 3 weeks for all 3 of them.

At her age, breeding is beginning to be dangerous, as she has bones in her hip that are about to fuse together. If the pups are born after they do so, the delivery is likely to kill the mother.

Finally, there is already a guinea pig overpopulation. There is no point in breeding them. If you want more, adopt.

Answer 4

Some animals just prefer to NOT become breeders.

Why do you want to breed your guinea pigs, anyways? Are they a certain breed? Doubtful. Guinea pigs aren't easy to find new homes for!

Just do a Petfinder.com search on Guinea Pigs, and I'm sure you'll see quite a few, in shelters locally that are there due to breeding and/or people getting bored of their new pets.

Answer 5

I think your female guinea pig is a lesbian and she doesn't like males. The same thing happened with my male rat. He was gay and didn't want anything to do with my fine female rat.
