All dogs are really just astral projections of mutated alien spaghetti.

In other areas of the universe, light years away, exists a planet full of alien spaghetti. You do not even have to question it because this is merely simple logic.

The spaghetti that was once born there mutated over time to adapt to their environment – similarly to animals here.

This fact would explain why it is common for dogs to obnoxiously bark at seemingly nothing. They are simply shocked light years away by the big evil pasta monster, nigatoni.

That is another story though. I think everyone is convinced by now of my quite insightful discovery, so I’ll just leave this here to further educate you simple minded people.
