To safely keep your newborn puppy warm at night, follow these steps:
Provide a warm, draft-free environment: Keep the whelping area away from doors, windows, or air vents that could create drafts. Ensure the room temperature is kept around 85-90°F (29-32°C) for the first week and then gradually decrease to about 75°F (24°C) by the fourth week. Use a heating pad or heat lamp: Place a heating pad set on a low temperature or a heat lamp positioned at a safe distance, ensuring it's not too hot or directly touching the puppies. Also, ensure the heat source covers only half of the whelping area, so the puppies can move to a cooler spot if they feel too warm. Provide blankets and nesting materials: Provide soft blankets or towels for the puppies to snuggle in. Make sure the materials are clean and changed regularly to maintain hygiene. Encourage the mother to keep the puppies warm: A healthy mother dog will instinctively keep them warm by lying close to them and curling around them. Ensure she has enough space and comfort to do so. Monitor the puppies' behavior: Warm and comfortable puppies will sleep and nurse peacefully. However, if you notice them constantly crying, huddling together, or appearing listless, it could be a sign that they are too cold, and you should adjust the heat source accordingly. Always check the puppies' temperature and comfort levels, and consult your veterinarian if you have concerns about their well-being.
