Listen, when living with pets, there's a certain order in the house. You have to accommodate certain things for them just like you would with any other roommate, set some expectations and limits, and don't be surprised when - if you violate one of those house rules - they call you out on it.
This gentle doggo definitely wasn't afraid of letting his human know that a limit has been crossed for it. Its spot on the couch has been cruelly stolen, and it had no choice but to stand its ground and remind its human that this is where it farts, so the human simply must move aside.
The video has a happy ending though, don't worry. Things go back to the order that they were supposed to have.
