The first televisions sold refreshed the image on the screen about 60 times per second. The way humans perceive time, that looks like a continuously moving image. To a dog and most other animals, that looks like a flickering series of still images. Predator and prey animals process information faster than we do; that’s why they have such good reflexes. (Newer TVs have much faster refresh rates, so they can look realistic to animals).
You may think you’re smarter than your dog, and maybe you are, but your dog processes information about twice as fast.
It’s relativity of a different sort. Consciousness is a weird thing, and it’s even weirder when you consider what consciousness is like for other living things. You are to a deer as a turtle is to you.
