Newborn feces are actually called meconium, and they look like black tar, sometimes with a slight dark olive green or yellow tinge. After the first few days of passing meconium and drinking milk, feces usually turn to a light yellow color.
The first stool/poop a newborn pup/human takes is a very sticky greenish black and is called meconium.
Because what you eat effects the color of you poop. If you poop is green or more likely to be brown that's good because it means you healthy. If your poop appears to be different then usually you should contact your doctor.
