Good nutrition is important throughout your dog’s life, but it becomes especially important during pregnancy. A balanced diet for a pregnant dog helps support the mother’s health while providing the energy and nutrients her developing puppies need.
However, feeding a pregnant dog isn’t simply a matter of giving her more food as soon as you learn she’s expecting. Her nutritional needs change throughout pregnancy, and overfeeding early on can be just as problematic as not providing enough nutrition later.
Understanding when to increase food, what type of food to offer, and which supplements to avoid can help support a healthy pregnancy and prepare your dog for nursing her puppies.
What Should You Feed a Pregnant Dog?
Before breeding, a dog should ideally be at a healthy body weight and eating a complete and balanced diet appropriate for her life stage. Maintaining a healthy weight is important because being significantly overweight or underweight can increase the risk of problems during pregnancy and delivery.
During the first several weeks of pregnancy, a healthy dog typically doesn’t require a significant increase in calories. Most fetal growth occurs later in pregnancy, so immediately increasing her portions can lead to unnecessary weight gain.
As pregnancy progresses, however, her nutritional needs change considerably. During the final weeks, a veterinarian may recommend transitioning to an energy-dense food formulated for growth and reproduction, such as an appropriate puppy food.
The best dog food for pregnant dogs should be complete and balanced and provide sufficient calories, protein, fat, vitamins, and minerals to support pregnancy. Your veterinarian can recommend a diet based on your dog’s age, breed, body condition, health, and expected litter size.
Fresh, clean water should also be available at all times throughout pregnancy and nursing.
Feeding During the First Half of Pregnancy
A dog’s pregnancy typically lasts about 63 days, although the exact length can vary. During approximately the first four to five weeks, the developing puppies remain relatively small, and the mother’s energy requirements don’t increase dramatically.
For this reason, a healthy dog generally doesn’t need substantially more food during early pregnancy. Continue feeding an appropriate complete and balanced diet in the amount recommended for maintaining a healthy body condition unless your veterinarian tells you otherwise.
Overfeeding during this stage can cause the mother to gain excess body fat. This can make pregnancy and delivery more difficult and may increase the risk of complications.
Some dogs experience a temporary decrease in appetite during early pregnancy. A brief period of reduced interest in food can occur, but contact your veterinarian if your dog stops eating completely, seems sick, vomits repeatedly, becomes unusually lethargic, or you have any other concerns about her health.
Feeding During the Last Weeks of Pregnancy
The final third of pregnancy is when nutrition becomes especially important. The puppies grow rapidly during this period, creating a much greater demand for calories and nutrients.
Your veterinarian may recommend gradually increasing the amount your dog eats as she approaches delivery. Rather than making a sudden change, increase her food according to her body condition and veterinary recommendations.
This is also when switching to an appropriate pregnant dog food or puppy formula may be useful. Foods formulated for growth and reproduction tend to be more energy-dense than standard adult maintenance foods. That allows the mother to get more calories and nutrients without having to consume an impractically large amount of food.
When choosing dog food for pregnant dogs, check the nutritional adequacy statement on the package. A veterinarian can help you determine whether a particular formula is appropriate for gestation and lactation.
Whenever changing foods, transition gradually when possible. A sudden diet change can cause digestive upset, which is particularly undesirable during pregnancy.
How Often Should You Feed a Pregnant Dog?
As the puppies grow, they take up more space in the mother’s abdomen. This can make it uncomfortable for her to eat a large meal at once, particularly if she’s carrying a large litter.
Instead of offering one or two large meals, consider dividing her daily food allowance into several smaller meals. This can make it easier for her to consume enough calories without becoming overly full.
The exact amount of food a pregnant dog needs depends on several factors, including:
- Her size and body condition
- The calorie content of her food
- Her activity level
- Her stage of pregnancy
- The number of puppies she’s carrying
- Any underlying health conditions
Rather than relying on a one-size-fits-all feeding amount, monitor your dog’s body condition and appetite and work with your veterinarian to adjust her diet as necessary.
Providing too little nutrition during late pregnancy can be dangerous. Severe nutritional or energy deficiencies can contribute to serious metabolic complications and put both the mother and puppies at risk.
What Happens to Appetite Before Labor?
As delivery approaches, your dog’s appetite may decrease. Some dogs eat much less than usual or temporarily stop eating before labor begins.
A decreased appetite can occur as part of the normal changes surrounding labor, but appetite alone isn’t a reliable way to predict exactly when puppies will arrive.
Continue offering food and fresh water, but don’t force your dog to eat. If she refuses food and also appears ill, weak, painful, or unusually lethargic, contact your veterinarian.
As your dog approaches her expected delivery date, make sure you’re familiar with the signs of labor as well as warning signs that may indicate a problem. Having your veterinarian’s contact information and the number of a nearby emergency veterinary hospital readily available is also a good idea.
Does a Pregnant Dog Need Prenatal Vitamins?
Pet parents may wonder whether they should give their dog supplements during pregnancy. After all, prenatal vitamins are routinely recommended during human pregnancy. But prenatal vitamins for dogs aren’t automatically necessary or beneficial.
If your dog is eating a complete and balanced diet formulated appropriately for pregnancy, additional vitamins and minerals usually shouldn’t be added unless your veterinarian recommends them.
More isn’t necessarily better when it comes to nutrition. Excessive amounts of certain vitamins and minerals can cause problems for the mother or interfere with normal puppy development.
Never give your dog human prenatal vitamins. Human supplements may contain inappropriate amounts of certain nutrients or other ingredients that aren’t suitable for dogs.
If you think your dog’s diet may be lacking something, talk to your veterinarian before adding prenatal vitamins for dogs or any other nutritional supplement.
Should You Give a Pregnant Dog Calcium Supplements?
Calcium deserves special attention because giving extra calcium during pregnancy may seem like a good way to support developing puppies. However, routine calcium supplementation during pregnancy is generally not recommended.
Giving unnecessary calcium during pregnancy can interfere with the mother’s normal regulation of calcium and potentially increase her risk of developing eclampsia during lactation. Eclampsia, also known as hypocalcemia or “milk fever,” is a potentially life-threatening drop in blood calcium that most commonly occurs while a mother is nursing puppies.
For this reason, don’t give a pregnant dog calcium supplements unless your veterinarian has specifically instructed you to do so.
A complete and balanced diet appropriate for gestation and lactation should provide the necessary amounts of calcium and other minerals in the proper proportions.
Nutrition After the Puppies Are Born
Your dog’s nutritional needs don’t return to normal immediately after delivery. In fact, lactation can place even greater energy demands on her body than pregnancy.
Producing enough milk for a growing litter requires substantial calories and water. Depending on litter size and the stage of lactation, a nursing mother may need considerably more food than she ate before pregnancy.
Continue feeding an energy-dense diet appropriate for growth and reproduction, and make sure fresh water is always readily available. Multiple meals or free-choice feeding may be appropriate for some nursing dogs, depending on your veterinarian’s recommendations.
Monitor the mother’s body condition throughout nursing. Weight loss can occur because of the tremendous energy demands of milk production, but excessive weight loss, poor appetite, weakness, tremors, abnormal behavior, or difficulty caring for the puppies warrants veterinary attention.
The Bottom Line on Feeding a Pregnant Dog
The ideal diet for a pregnant dog changes as pregnancy progresses. During the first several weeks, most healthy dogs don’t need a dramatic increase in food. During the final weeks, however, rapidly developing puppies significantly increase the mother’s nutritional and energy requirements.
An appropriate, calorie-dense pregnant dog food or puppy formula can help meet these increased needs, while smaller, more frequent meals can make eating easier as the puppies take up more room.
Avoid adding supplements, including calcium or prenatal vitamins for dogs, without veterinary guidance. A complete and balanced diet should provide the nutrients most pregnant dogs need.
Finally, keep your veterinarian involved throughout pregnancy. Regular veterinary care, appropriate nutrition, and careful monitoring can help give both the mother and her puppies the best possible start.
