Nutritional Needs During Dog Pregnancy and Postpartum Care

Dogs are polytocous animals and may carry several puppies at once. Proper nutrition management is key to keeping both the mother and all puppies healthy. Energy requirements increase dramatically during late pregnancy and lactation, and owners need to adjust food content and portions according to different stages.

## Dog Pregnancy Timeline

A dog's pregnancy lasts approximately 58-68 days, with an average of about 63 days. It can be divided into three stages:

* **Early Stage (Weeks 1-4)**: Embryo implantation, no obvious physical changes
* **Middle Stage (Weeks 5-6)**: Fetuses begin rapid development, abdomen gradually enlarges
* **Late Stage (Weeks 7-9)**: Fetuses mature, preparing for delivery

## Nutritional Needs by Pregnancy Stage

### Early Pregnancy (Weeks 1-4)

No major dietary changes are needed at this stage:
* Maintain the original balanced nutrition
* Keep food portions normal
* Avoid overfeeding to prevent abnormal weight gain
* Ensure good food quality

### Mid to Late Pregnancy (Weeks 5-9)

From the fifth week, fetuses develop rapidly and the mother's nutritional needs increase significantly:

* Gradually increase food portions; by delivery, increase by 35-50%
* Switch to high-protein, high-calorie food (pregnant dog formula or puppy formula)
* Feed small meals frequently, 3-4 times daily
* Ensure adequate calcium and phosphorus
* Supplement with quality protein sources

**Suitable Food Supplements:**
* Hard-boiled eggs
* Lean meat (chicken, beef)
* Liver (in moderation)
* Quality dog canned food

## Lactation Period Nutritional Needs

Lactation is when the mother's nutritional needs are highest, as milk production requires enormous energy.

### Energy Requirement Changes

* Immediately postpartum: Energy needs increase to **200%** (2 times normal)
* 3-4 weeks postpartum (peak lactation): Needs **300%** (3 times normal)
* After puppies begin weaning: Gradually reduce back to normal portions

### Dietary Guidelines

**Small, Frequent Meals**
* Feed 4-5 meals daily
* Avoid large single meals that cause gastrointestinal discomfort
* Always provide plenty of fresh water

**High Protein, High Fat**
* Choose puppy formula or high-energy food (many brands use the same formula for puppies and pregnant dogs)
* Increase protein sources like meat and eggs
* Ensure sufficient fat intake to support milk production

### Weight Monitoring

Lactating mothers may lose weight, which is normal. However, note that:
* Weight loss should not exceed 10% of original body weight
* If too thin, it indicates insufficient nutritional intake
* Adjust food content and portions as necessary

## Postpartum Care Points

### Whelping Box Preparation

* Choose a quiet, warm corner
* Line with clean, soft towels or blankets
* Avoid outside disturbances
* Maintain appropriate temperature (puppies cannot regulate their own body temperature)

### Mother Dog Care

* Allow the mother to rest fully after delivery
* Ensure fresh water and food are always available
* Watch for abnormal discharge or fever
* Keep the whelping area clean and dry

### Puppy Care

* Confirm each puppy is nursing successfully
* Puppies should nurse every 2-3 hours
* If mother's milk is insufficient, prepare puppy formula
* Important: Never feed cow's milk or goat's milk—it easily causes diarrhea

## When to See a Veterinarian?

**Mother Dog Abnormalities:**
* Delivery not completed after 24 hours
* Continuous heavy bleeding postpartum
* Fever, complete loss of appetite
* Red, swollen, painful mammary glands (possible mastitis)
* Indifference toward puppies

**Puppy Abnormalities:**
* Not nursing after birth
* Continuous crying
* Weight loss instead of gain
* Difficulty breathing

## Weaning and Follow-Up Care

Puppies typically start trying solid food at 3-4 weeks of age and are fully weaned at 6-8 weeks.

* Gradually reduce mother's food portions during weaning
* Once puppies start eating solid food, mother's milk production naturally decreases
* After complete weaning, the mother returns to normal body condition in about 1-2 weeks

Pregnancy and lactation place the greatest physical burden on mother dogs. Good nutrition management not only ensures the mother's health but also provides puppies with the best developmental environment. For planned breeding, it's recommended to start adjusting the mother's nutritional status before mating.
