It’s not every day you experience something so incredibly fun, you wish it would never end.

That’s what playtime was for this ripped boxer, who adamantly refuses to believe that his playtime for the day is over.

The human drags the suddenly bipedal dog, neither of them giving in and letting go of the blue ball. But with muscles like that, we’re almost surprised the boxer didn’t find victory in this particular battle.

But seriously, what a party pooper.
