Had a dog that would press her nose right up to an ipad screen and move her face around to follow the squirrel, bird, or dog that interested her. She would get very excited about it. She also watched TV. At one point sitting on hind legs trying to elevate off the bed to be inline with the center of the image.

Only one of my dogs appears to recognize things in the TV. She'll bark at something on screen, and my other dog will run to a window or door trying to figure what he missed. Always wondered why...
