Dogs notice and understand pictures they see on the television screen, as well as the sounds that accompany them. Digital and HD technology has improved the TV experience for dogs, says Janet Miller.

There is even a channel especially for dogs on HDTV called DogTV. The channel has more frames per second than regular television and is specifically colored for a dog’s specific sight. Since dogs can process visual information faster than humans, what they see is quite different from what we see.
