@x1extreme1x Dog watches TV intently and hates most of it. We pretty much can't watch TV with him around. Old tube TVs, HD TVs it doesn't matter: he sees them all.
Here is a not inclusive list of the things he hates on the TV and will bark at incessantly: animals of any type, dogs and horses especially, 3D animated characters, people physically fighting or arguing animatedly, certain sounds like the Jeopardy daily double or out of time sound (I shit you not). Also, guns being fired, jump scares and even just music swells leading to a tense moment.
Any time any TV is on he stares at it waiting for moments like these to occur.
I really need to post a video, it's absolutely nuts.
