One of the questions I get asked a lot is how to tell if a guinea pig is pregnant. I don’t have all the details, but here are a couple of things you can look for. The first thing you can do if your pig is going into heat is to palpate her. When she is in heat, her fur will be warmer and it may seem as though she is ready to give birth. If this is the case, she will be moving around a lot and you may notice that she is walking slower than usual.
Another way to tell if a guinea pig is pregnant is to pay attention to her behavior. A pregnant pig will usually be cuddling and sleeping more than normal. Also, her litter will be taking longer than normal to develop. These are all signs that she is ready for parenthood. You should also keep an eye out for any changes in the size of her stomach or in her eating habits because these can indicate that she is ready to give birth.
If all of these things are true and you suspect that your pig is going into labor, then you need to take her to the vet immediately. You can tell if she is in labor by observing the way she moves. If she is not moving around much or shows any signs of struggling, she is most likely having a vaginal birth. If she is in labor and has struggled with delivery, then she may be having a large baby.
