The newborn Chihuahua puppies are completely blind, deaf, and toothless. They are not able to see and hear anything for few weeks. however, they have the sense of smell and touch. Which is how they get to their mother. The puppies can track the scent of their mother and get to them by crawling, which also helps in their muscle development.
