When we last posted a collection of before-and-after dog photos, we were overwhelmed by a flood of photos from our readers their own photos of dogs growing up. We love these photos as much as you guys do, so here's a new list of before-and-after dog photos for you guys to enjoy and add to!

One thing you'll probably notice from these photos is that dogs grow REALLY fast! Depending on the size of your pup's breed, they can reach their full size in 6 to 18 months with some of the largest breeds sometimes taking up to 2 years.

Feel free to add photos of your own pooch from their earliest puppyhood and how they look now. Write the time elapsed between the two photos too so that we know how much they've grown!

Dogs eyes can change just like babies do. Most all babies are born with blue eyes then around 6-9 months their true eye color will show.
