Puppies are born approximately nine weeks from the time of conception. In the first six weeks of pregnancy, they don't grow significantly, so it's generally not necessary to increase the mother's food. However, during the last three weeks of pregnancy, puppies grow substantially, increasing their size by approximately 60 to 70%.
During these last three weeks, the mother's food and energy requirements increase up to 50%. Consider moving your expectant dog from her regular maintenance formula to a formula such as Iams® Smart Puppy™, which can provide the extra nutrients her body needs. Be sure to read the labels carefully and follow the feeding instructions for pregnant dogs. (For example, Iams ProActive Health™ Smart Puppy Large Breed is formulated specifically for the controlled growth needs of large-breed puppies and should not be fed to pregnant or nursing dogs.)
Nutrition for Nursing Mothers
One of the most important things you can do for your pregnant dog is to provide her with a high-quality, well-balanced food formulated to support the additional caloric requirements of pregnancy. Also, this proper nutrition during the nursing stage is essential to the overall health and well-being of her puppies.
When the puppies are born, their growth depends on acquiring adequate amounts of milk from the mother. So, the quality of the food the mother eats is particularly important, as the mother must eat, digest, absorb and use large amounts of nutrients to produce milk to support the growth and development of several puppies. Most nursing mothers need almost twice as much food while they're nursing as they do before getting pregnant.
In addition to the demand for extra energy, nursing increases a dog's need for water. It is important to make sure she always has fresh water.
Keep in mind that an expectant dog's food requirements vary depending on the breed of dog, size and the number of puppies — so, it is important to work closely with your veterinarian throughout the pregnancy. He or she can help you ensure that your dog and her litter remain in good health.
