When Can My Pitbull Get Pregnant?

By Bethany Tate

Most pitbulls can get pregnant between 1 and 2 years old, but that doesn’t necessarily mean they should get pregnant at that time. Pitbulls are not fully grown until they are 12 to 18 months old. Even though they may be sexually mature after 12 months, it’s better to weight until a pit bull is full grown to try for a pregnancy. 

Some vets recommend not to breed a pit bull bitch until she is on her third or fourth cycle. Breeding earlier puts her at greater risk for physical or even behavioral problems. It’s also a good idea to wait before breeding to see if your pitbull has any genetic disorders that could be inherited by her puppies. 

How to tell if a pit bull is pregnant

Signs of pregnancy in pit bulls include

  • Clear vaginal discharge
  • An increased appetite
  • Nipple Enlargement
  • Nesting
  • Belly is swollen
  • Your pit bull is lethargic

If you notice any of these symptoms in your pit bull it’s best to contact your local vet and schedule a visit to confirm whether or not your pit bull is pregnant. A veterinarian will likely run a series of tests to see if your pit bull is pregnant and check on her health and the health of her litter. These tests could include a blood test or ultrasound. 

If your pit bull is four months into the pregnancy then the vet is likely to do a physical examination. At six weeks an x-ray may be performed. 

How to prepare for a pit bull pregnancy 

If you are planning on breeding your pit bull there are some steps you can take to help ensure a healthy pregnancy and birth. Both of these tips are general health tips, as good general health for your pit bull will help her have a good pregnancy. 

Proper nutrition

You want to make sure your would-be pit bull mother is on a healthy diet and getting all the nutrition her body needs. If you already are feeding her a high quality dog food and she’s at a healthy weight then you won’t have to make any special changes to her diet. If your dog is underweight or overweight, or if you are unsure about whether or not you’re feeding your pit bull the right food it’s best to consult your vet for a personal recommendation based on your pitbull’s unique situation. 


Make sure your pit bull gets at least 30-45 minutes of exercise each day. This could include anything from walks, to active play time, or even a brisk stroll on a dog treadmill. Having your pitbull’s body at peak physical fitness will go along way toward helping her have a safe and successful pregnancy

Make your pitbull a whelping box

A whelping box can be made from material ranging from cardboard to wood. The most important attributes of a whelping box are its size and location. It should be big enough to comfortably fit your pitbull and her future puppies. It should also be placed somewhere that feels safe, quiet and cozy for your pit bull. If your pit bull doesn’t feel safe during delivery then it could lead to complications.
