Preparing for Your Dog's Pregnancy
Confirm pregnancy early. Visit your veterinarian around day 25-30 for an ultrasound to confirm pregnancy and get an accurate count of expected puppies.
Adjust nutrition gradually. Starting around week 5, transition to a high-quality puppy food that provides the extra calories and nutrients needed for fetal development.
Prepare a whelping area. Set up a quiet, clean, warm whelping box by week 7 so your dog can get comfortable with the space before delivery.
Know the signs of labor. Watch for temperature drops, restlessness, nesting behavior, and loss of appetite as indicators that whelping is near.
