While exploring the house one day, Mango the cavachon puppy stumbled onto a worthy adversary that he hadn’t spotted before on his adventures…a doorstopper!

To you and me it might seen like a simple innovation, designed to stop doors from slamming into walls, but Mango had never seen such a relentless foe before. No matter how many bites and kicks little Mango delivered, the doorstopper simply wouldn’t give up, springing back into place every time.

Rumor has it that a “bwongggggg” sound can still be heard coming from Mango’s house to this day. He’s not one to give up easily.
