Article: After at least 18 days, check if the sow is pregnant. You can do this yourself - see How to Tell if Your Guinea Pig Is Pregnant - but only a vet will be able to say for sure.  A pregnant female may exhibits several symptoms of pregnancy including distended abdomen and increased food and water consumption. A sow may eat 2-3 times her normal amount when pregnant.  A vet may also determine an estimated delivery date. It may take several heat cycles for the sow to become pregnant. Be patient so that you do not stress your guinea pigs. Once you’re sow becomes pregnant, the gestation period will 63-70 days. During this time it is important to prevent stress as much as possible.  Do not make any changes to the sow’s cage and reduce exposure to anything that may cause stress, such as loud noises.  Handle the sow minimally during the pregnancy and not at all during the last two weeks. You can coax her on to a towel or box for the delivery.  You can leave the boar in the cage with the sow to comfort her.  It’s advisable to remove other guinea pigs from the sow’s space and allow her to litter alone. The amount of food and water a sow consumes will increase during pregnancy. Give her more food to help ensure she gets much needed nutrients to support the developing pups. Increase the amount of fresh vegetables on offer to 1½ to 2 cups per day. Pregnancy is very risk for sows because pups are large. Check the sow thoroughly daily by looking for any signs of illness and weighing the sow.  The signs of illness may include crusty eyes, nose, or ears; and a thinning or patchy coat.  The sow should gradually put on weight, though how much depends on the individual and size of the litter. Check she is eating. An early warning sign of pregnancy toxaemia is lack of appetite. Any pregnant sow that doesn't eat for more than 12 hours should see a veterinarian. If you notice any problems with your guinea pig, including lack of movement of her unborn pups, consult a vet. You should be prepared for your sow to give birth at around nine weeks. Making sure you’re prepared for the birth with medical supplies can help you handle any complications that may arise.  Guinea pigs don’t show any outward signs of impending birth and don’t make any specific preparations for labor so it may be hard to tell exactly when the sow will give birth.  You may notice a slight widening of the pelvic bones in the sow right before she gives birth.  Stock up on a syringe, which you may need to clean out a newborn pups mouth.  It is a good idea to alert a vet when the sow reaches nine weeks so they are aware that they may need to intervene and can be on hand to attend to the sow immediately if a complication does arise. It takes guinea pigs 10-30 minutes to give birth if a sow has no complications. If the labor takes longer than an hour, call your vet or take the sow for medical treatment.  Do not crowd the female while she is laboring. Have only one person with her to oversee the birth and do not touch her.  A sow should give birth every 5-10 minutes. A sow will usually have between 1-5 pups.  The sow will give birth by sitting up and hunching over or by squatting.  Get your guinea pig to a doctor if the labor becomes complicated. For example,  if it takes longer than one hour, there more than 15 minutes between pups, if she exhibits excessive bleeding, or making extreme stress calls.
