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.
A puppy nibbling on your fingers may seem cute and harmless, but when he grows up, biting can become a hard habit to break. Join Expert Pet Trainer Kathy Santo as she explains the reasons puppies bite and what you can do to change their behavior.
Hi, I'm Kathy Santo with IAMS, and today we're going to discuss the dangers of allowing puppy biting, the importance of playing correctly, and how to stop the unwanted biting behavior.
It's normal and even cute when your puppy nibbles and lunges at your hands. Since your puppy has been exposed to only other puppies in the litter, who naturally play with biting and mouthing, it would make perfect sense why he would assume that playing with you wouldn't be different. But as puppies' teeth grow, and their bodies become stronger, what was once cute nibbling eventually turns into uncomfortable, or even dangerous, rough play and bites.
Since biting is an unacceptable type of play, it's important to teach your pup how to enjoy playing games with toys instead of your hand. Playing is a healthy, natural activity that helps build the bond between you and your puppy. This also affects your puppy's train ability-- sitting, waiting, learning tricks, not pulling on the leash, even to stop biting.
Before teaching your puppy not to bite, it's important to train your puppy to decrease bite pressure. Allow your puppy to begin mouthing and nibbling at your hand. When he bites down hard, yell 'ouch,' so he's startled and stops for a second. Continue allowing him to mouth your hand, making sure to speak up every time he bites too hard, so your puppy can learn your threshold for what is acceptable and what isn't.
Once your puppy understands your feedback about the strength of his bite, you can begin to reduce biting. The best way to teach your puppy not to bite is to redirect him to a toy or a chew bone. Simply give your dog a firm 'no,' and replace whatever he was biting with something he is allowed to chew.
If your puppy is three to six months old, there is a good chance he may be teething, so he might be trying to reduce discomfort by chewing. Try giving him an ice cube to chew on. It'll numb his gums and help alleviate the pain.
My favorite trick to get puppies to stop biting is to exaggerate, and pretend they've injured me, their friend. By pretending their nip actually hurt you, by pulling your hand away, yelling 'ouch,' and stop playing, you're replicating what other litter mates would do if another puppy were to cause them pain.
Managing and controlling puppy biting problems can be a major challenge for dog lovers. Puppy biting or nipping starts out as a bit of fun, but needs to be controlled quickly to avoid ongoing problems. Training your dog depends on a good relationship built on love and trust. It takes time to build a working partnership, and the more time and patience you have with your puppy from day one, the more obedient he'll be. Dogs want to please.
