Warning: Entanglement is a state where two or more particles are connected in such a way that the state of one particle cannot be described without mentioning the others. This is also true for our Quantum Schrödinger Dogs. They can only be separated by a sufficiently thick wall.
Our Quantum Schrödinger Dog, "Entanglementy," is a peculiar creature. When separated from its entangled partner, "Schrödingerian," it will not collapse into a definite state until observed by a human.
However, when reunited, the dogs will instantly be in the same state as if they never parted. It's like they're two peas in a pod... of uncertainty.
We have several theories on how to handle Entanglementy: Separation Anxiety Disorder
Or, for those who dare, try Quantum Teleportation Treatments.
