Newborn puppies are essentially blind for the first 2 weeks of life. Their eyes don’t open until around 14 days old.
Puppies can't regulate body heat. They rely on skin contact with mom and littermates to maintain a temperature of 95°.
Need Constant Warmth
Puppies sleep almost around the clock their first few weeks. Waking mainly to nurse from mom.
Sleep 90% of the Day
All dogs descend from wolves. Early domestication occurred over 30,000 years ago.
Ancestors Were Fierce
Whines, yelps, grunts, barks communicate hunger, distress, contentment almost immediately
Make Distinct Noises
Mom stimulates elimination by licking puppies. Puppies can't poop/pee on their own initially.
Puppies weigh just 10-15 ounces at birth but reach 2 pounds in just 1 week's time!
