Newborn puppy care involves five important roles. These are to keep a clean environment, provide enough warmth, regular weigh-ins, to ensure good nutrition, and to socialize them well. It's important to keep the whelping box dry, warm, and clean during the puppies' growth. You will need to clean up the whelping box once a day for the first week to ensure the best newborn puppy care. To do this, avoid using household chemicals and only use pet-safe detergent when washing any towels. Be sure to disinfect the box and to replace any newspaper and bedding. As well as this, the whelping box should be between 85 and 90°F (29.5 and 32°C) for the first 4 days of your puppies' lives. After this point, the temperature can go down to a milder 80°F (26.7°C). You can use a heat lamp, space heater, or heating pads to achieve this temperature. Newborn puppies should be weighed once or twice a day. If your puppy is healthy, you should notice a steady daily increase in weight! As a general rule, a puppy's body weight should double by 7 to 10 days. If your puppy can't drink their mother's milk, you need to provide a high-quality canine milk replacer. Canine milk replacers should be enriched with amino acids, vitamins, and minerals.
