* Evolutionary Adaptation: Small size makes it easier for the mother dog to give birth. Larger puppies would be more difficult to deliver, increasing the risk of complications for both mother and pups.
* Immaturity: Puppies are born relatively underdeveloped compared to other animals. Their brains, muscles, and digestive systems need time to mature. This is why they rely heavily on their mother for nourishment and care.
* Survival: While small size makes birth easier, it also helps with survival. Small puppies can stay warm and safe huddled together under their mother, and they are less likely to attract predators.
* Nursing: Smaller puppies require less milk, making it easier for the mother to feed multiple pups. They also tend to nurse more frequently, stimulating milk production.
* Socialization: Smaller size allows for increased physical contact between puppies and their siblings, promoting early socialization and bonding.
It's important to note that while puppies are small, they grow rapidly in the first few weeks of life. This rapid growth is essential for their development and survival.
