Here's why:
* Different Growth Rates: Puppies grow and develop much faster than humans.
* No Simple Conversion: There's no exact formula to translate a puppy's age to human years.
* Breed Variations: Different dog breeds have different growth rates and lifespans.
Instead of trying to find a human equivalent, focus on these milestones for a 3-day-old puppy:
* Newborn Stage: They are completely dependent on their mother for warmth, nourishment, and care.
* Sleeping and Nursing: They spend most of their time sleeping and nursing.
* Developing Senses: Their senses are still developing.
* No Elimination Control: They can't control their bladders or bowels.
If you have a 3-day-old puppy, it's crucial to ensure their mother is caring for them properly. If you have concerns, contact a veterinarian immediately.
