Whether you've adopted a puppy and you're wondering when he'll calm down and stop chewing on everything — or you're simply curious about what puppies go through to become full-fledged dogs — this puppy timeline has the answers you're looking for. Puppies are born blind and deaf , with both their eyes and ears sealed shut. For their first two weeks of life, newborn pups experience the world entirely through touch and smell. During the third week their eyes and ears open, giving tiny pups a whole new way to experience life.

All dogs pass through the same puppy development stages. Small dog breeds develop more quickly and reach maturity at an earlier age than larger breeds. Each stage in development includes important milestones such as ears and eyes opening, learning to walk and starting to eat solid food.

If your puppy is six months old, you have likely watched him go through his fast-growing juvenile stage from age three to six months. Now that your puppy has reached six months of age, he can be considered an adolescent. During this time, your puppy's physical changes will slow down a bit.
