*~How We Develop**
Stage 2: 2 - 4 Weeks
The puppy's eyes will open at or around the beginning of this second stage of development. His new sense of sight will be limited and very sensitive, so to avoid eye damage, care must be taken to protect him from bright lights. Despite these limitations, the puppy will now begin to recognize and interact with things in his environment, including (most importantly!) his mother and littermates. Many experts consider this the "toddler" stage of development as the puppy becomes more alert and learns to crawl, stand, and ultimately walk. With this new mobility, he will also begin to attempt to better explore his surroundings.
