Is there anything as adorable as a new puppy?
The amazing thing is by their first week of life they’re already able to find each other and their mama using scent and heat receptors they have on their noses, as well as their sense of touch. In another 2 weeks they begin to see and hear somewhat, although those senses won’t be fully developed for another 2 weeks.
By the age of 5 weeks, the puppy has completely developed his sensory equipment to the level of an adult dog. That is incredible to me- think how long it takes a baby to complete her growth and abilities. If a 5 week old human baby developed that fast she’d be reading books and running across the lawn with her mother chasing after her in a panic.
It’s a good thing for us mother humans that our young take a little longer to develop.
