There’s gotta be something in the DNA of all dogs that makes them believe that they’re part puppy even when they’ve gotten older and much BIGGER.

But some pooches really take it to the extreme…like the ones you’re about to meet in the photos below.

All of these pups are full-grown adults now, yet they still insist on acting like little puppies with their owners.

And, as you can imagine, it’s both hilarious and heartwarming. So let’s meet these dogs that refuse to grow up! Enjoy!

1. You still think you’re a lap dog?

Something looks a little bit fishy here…

Well, what do you have to say for yourself?
