Stages of Dog Pregnancy Week by Week and Caring Tips

Understanding the Stages of Dog Pregnancy

When you find out your dog is expecting puppies, it's natural to feel excited but also anxious about what to expect. Knowing the stages of dog pregnancy day by day can help you provide the best care for your pregnant pooch.

Early Signs of Dog Pregnancy

During early pregnancy, your dog's body is already going through significant changes as it prepares for the demands of developing puppies. Here are some of the earliest signs that your dog may be expecting:

• Decreased appetite - Your dog may eat less than normal during the first few weeks as hormonal changes affect her digestion.
• Vomiting - Some morning sickness is common around 3-4 weeks into pregnancy as progesterone levels rise.
• Increased appetite - Once morning sickness passes, you'll notice your dog wants more food as the puppies grow.
• Weight gain - Your dog will start gaining weight soon after conception as the fetuses develop.
• Fatigue - The physical demands of pregnancy may leave your dog sleeping more than usual.

The First Trimester (Week 1-4)

The earliest and most vulnerable stage of pregnancy is the first trimester, roughly the first month after breeding. Here's what to expect day by day:

• Week 1 - Ovulation and fertilization occur around days 10-15 of the heat cycle. You'll notice your dog is less willing to breed at this point.
• Weeks 2-3 - The fertilized eggs travel to the uterus for implantation around weeks 2-3. Your dog will seem back to normal behaviorally.
• Week 4 - Morning sickness and appetite changes emerge as hormone levels shift and the placenta forms.

The Second Trimester (Week 5-8)

During the second trimester from weeks 5-8, the most rapid fetal development begins as the puppies grow from embryos into fetuses:

• Weeks 5-6 - The embryos embed into the uterus lining, the neural tube brain and spinal cord begins forming, and the heart starts beating.
• Weeks 7-8 - Eyes, legs, distinct features take shape. Bones begin hardening, and the puppies are kicking actively now.

The Final Trimester (Week 9 to Birth)

The last 3 weeks are when your dog will start looking visibly and uncomfortably pregnant until labor finally begins:

• Week 9 - Rapid fetal growth leads to an expanding belly. Puppy movement is easy to see from the outside now.
• Week 10 - Your dog's appetite will peak to nourish the fast-growing puppies. Her mammary glands may start producing milk.
• Week 11 - Few physical changes now as puppies use this last week to gain weight before birth.
• Week 12 - Pregnancy lasts 58-68 days total. Most dogs go into labor around 63 days from their last breeding.

Caring for Your Dog During Pregnancy

Now that you know what to expect during your dog's pregnancy week by week, here is how to best support her:

Nutrition

Boosting calories and nutrients in your pregnant dog's diet will help her avoid excessive weight loss during nursing. Here are some tips:

• Feed a high quality puppy food for extra calories and nutrients important for growth like protein, fat, calcium, etc.
• Work with your vet to adjust portions to avoid obesity.
• Supplement with chewable prenatal vitamins to provide important pregnancy vitamins and minerals if needed.

Exercise

Light exercise remains healthy during pregnancy but should taper down as your dog's belly swells:

• Avoid strenuous exercise that could cause injury from weeks 5 onwards.
• Short, gentle walks are ideal to maintain muscle tone without taxing your dog.
• Be cautious of slippery floors that could cause falls later in pregnancy.

Birthing Preparations

Gather essential supplies for your dog by week 8 so you're fully ready when labor begins:

• Designate a quiet, comfortable whelping box with plush bedding where your dog can nest when labor nears.
• Have clean towels, nursing supplement bottles, and sterile surgical equipment in case assistance is needed.
• Find an emergency vet clinic in case complications require professional help.

Knowing what to expect during your pregnant dog's trimesters reduces stress for both you and your beloved pooch. Follow these tips to help support her health until the puppies safely arrive.
