FAQs
What does a dog look like at 4 weeks pregnant?
At 4 weeks, your dog’s abdomen will be slightly enlarged and firm. Nipples become more prominent and pink. Some dogs develop a clear mucus discharge. An ultrasound at this stage can confirm pregnancy and detect foetal heartbeats.
How many puppies can a dog have?
Litter sizes range from 1 to 12+ puppies depending on breed size. Small breeds typically have 1-4 puppies; large breeds 6-10+. A veterinary X-ray at week 7 is the most accurate way to count expected puppies before birth.
