I had a Corgi that watched television. Note - I’m not talking about “seeing moving images”. I’m talking about WATCHING. He liked light comedy, but hated police procedurals and would leave the room in disgust. In particular, he loved Susanne Sommers in Three’s Company and Carrie in Sex and the City. He watched America’s funniest videos for the animal videos. My FIL thought that we were insane until my dog sat down with him and watched a Sopranos marathon. We had a Tivo, and when my FIL would go to the bathroom he would pause it and the dog would give him a dirty look. After that, he believed.
The weird thing was that he could even understand cartoon representations of dogs. Look at “Snoopy” in Peanuts. He immediately recognized the cartoon dog as a dog. We tested him with a stick figure drawing of a dog. He barked at it!
Of course, with my dog watching television, that demonstrated that he was as smart as many people, which is not actually saying much...
We had a Rottie that was addicted to TV and was the same way as your Corgi. We could not watch Nature unless it was about bugs or volcanoes. Our girl recognized the lead-in music to Frasier and would head for the TV when it came on so she could watch Eddie. She would go nutzo when Eddie was on. She also when nuts when a rodeo was on, especially the calf roping event.
They really are wonderful friends. We have had Rotties for almost 40 years.
