A time-lapse video showing how two golden retrievers grew up has gone viral.

The 90-second video, shot by Chris Cardinal of Arizona, shows the dogs from 11 weeks to 46 weeks of age as if they "grow up overnight," Live 105 reported.

The puppies, Colby and Bleu, were filmed for nine months in their nightly "dinner run", where we can notice them grow and how much they've changed.

But apart from the changes, we can see how they also stayed the same in their apparent joy and excitement for dinner. Even though the two dogs have aged, they still have that little puppy in them as they race to the kitchen for food, which could be an adorable thing for the pet owner.

The pair,  known as the "time-lapse puppies," were born in July 2014, and they always seem like racing each other to their bowls, The Telegraph reported.

The video was posted on YouTube on June 21, and it already has over 7 million views.

Colby and Bleu are also on Instagram with around 5,000 followers and counting.
