Dog Poop Shoot

A dogs poop shoot has two functions, one of which is to poop, the other one is that it can be used as a reset button if your dog is having issues.

Joe: Dude, I think my dog is about to die... it's having heart problems.
Yuri: Nah bro, if you just press your dog poop shoot, it will reset and be fine again.
Joe: Thanks bro!!
