Pregnancy and nursing are not only responsible for many changes in a dog's body, but for changes in her lifestyle as well. If your dog is pregnant or nursing, pay special attention to her changing nutritional needs as she carries, delivers and nurses her puppies.
If you're planning to breed your female dog, it’s important to assess her body condition well in advance of breeding. Because of the physical demands of pregnancy and nursing, a dog with less-than-ideal health can experience problems:
Be sure to feed the proper amounts of a complete and balanced diet. This will support the mother's healthy weight and body condition before breeding and help maintain her health and that of her babies throughout pregnancy and lactation.
The gestation period for dogs is nine weeks. Pregnant dogs gain weight only slightly until about the sixth week, and then gain weight rapidly.
The energy requirements of pregnant dogs are reflected in the pattern of weight gain. Pregnant dogs will need to consume 25% to 50% more than their normal food intake by the end of pregnancy, but energy requirements do not increase until about the sixth week.
The best diet for pregnant and nursing dogs is a high-quality, nutrient-dense pet food formulated for all life stages or for growth. Although puppy diets are generally recommended for pregnant or nursing dogs, large-breed puppy formulas may not be appropriate for this use due to their adjusted energy and mineral content.
Pregnant dogs lose weight after giving birth, but their nutritional needs increase dramatically. Depending on litter size, nursing dogs might need two to three times their normal food requirement to nourish their pups. Be sure your nursing mom has plenty of water so she can generate the milk volume she needs to feed the litter.
To help your nursing dog get enough nutrition, you can try several tactics:

By four to five weeks after birth, most puppies are showing an interest in their mother’s food. Gradually, the puppies will begin eating more solid food and nursing less. At the same time, the nursing mother will usually begin eating less. Most puppies are completely weaned around age 7 to 8 weeks. By this time, the mother's energy requirement is back to normal, and she should be eating her normal pre-pregnancy diet.
By now we all know obesity is unhealthy—for both people and pets. But do you know just how many health problems it can cause for your dog? Diabetes, bone and joint damage, decreased liver function, heart disease, increased blood pressure, and a heightened risk of cancer are just a few of the serious health issues caused by obesity. That’s a scary list. Protect your pooch by taking a proactive approach to keeping the pounds off. Here are some ways to do it.
Dogs do better with a controlled amount of food on a schedule. While some dogs can handle eating from an always-full and ever-present dog bowl, most will overeat if food is always available.
There are lots of dog foods out there, all offering something different. When it comes to keeping obesity in check, IAMS™ ProActive Health™ Adult Weight Control and IAMS Healthy Naturals™ Weight Management with Chicken formulas are great choices.
Your dog’s your pal, so it’s difficult not to share your tasty bacon or a bite of steak with him when he gives you those big, pleading eyes. But trust us—it’s worth it to resist. Feeding Fido “people food” ups his food and fat intake significantly. Plus, it creates bad habits: A dog that’s not fed from the table won’t learn to beg.
Obviously, a great way to keep your dog trim and fit is with some good exercise sessions. When you don’t have a lot of time, do short sessions of fetch or tug-of-war. Take it to the next level by jogging with your dog, tossing the Frisbee®, or starting agility training. And here’s a bonus: A dog that gets enough exercise is less likely to act out.
Of course you want to reward your dog when he’s good—but don’t forget that those treats can add up. Pay attention to the calorie and fat content of the treats you give. More importantly, take note of how many goodies you’re doling out—and how often.
Most of the time, a dog is overweight because he’s taking in more calories than he’s burning. But it is possible that there is a larger problem at work. If you’ve tried maintaining your dog’s diet and increasing exercise and still aren’t seeing results, talk to your veterinarian about a possible thyroid or other metabolic disorder.
Don’t get discouraged if you slip up every once in a while or don’t see results right away. Battling obesity is done day to day—it’s about forming good habits and being disciplined. By following the tips above and showing a little dedication, you’ll be on your way to having a healthier, happier dog.
