By now, your sweet little doggo has been in this world for a couple weeks. They’ve been busy nursing, sleeping, opening their eyes, and hobbling around on their chubby legs. Get ready, because from week three to week five you will see even more exciting changes in your roly poly pup. As they continue to grow, they will interact more with their surroundings. This is a key time for sensory and physical development as your pup transitions from a helpless little newborn to rambunctious ball of fur! Even though they are a bit more independent, they still find safety in being near their mom. Count yourself lucky that you get to see your little one grow.  Over the next three weeks, watch for these major milestones. Â
