What indicates healthy newborn pups that do not require fostering?

Healthy newborn pups exhibit certain physical characteristics and behaviors that signify they are thriving and do not require fostering. A nice pink skin color is indicative of good circulation and oxygenation, which are crucial for survival and growth. This pink coloration suggests the pups are healthy and not suffering from hypoxia or other nutritional deficiencies.

Additionally, the presence of a milk spot, which is the area on the abdomen where milk fills the stomach after nursing, is a strong indicator that the pup is successfully nursing and receiving adequate nutrition from the mother. This is essential for their growth and overall health in the early stages of life.

In contrast, large size and the presence of fur can be misleading; while they might be markers of health in some cases, they alone do not provide a comprehensive view of the pup's well-being. White skin color and apathetic behavior are signs of possible health issues, as healthy puppies should be active and engaged with their environment. Signs of aggression towards siblings are not normal for newborns, as puppies typically display social behaviors and rely on their littermates for warmth and comfort during the early days of life.
