My yorkie watches TV a lot. The kennel we bought him from did not have a TV in their kennel, so the first one he ever saw was when we brought him home at four months of age. He has always been fascinated by the TV. His most hated commercial is the M&M running on the conveyor belt (like a tread mill). He will get out of bed and come flying to the living room to bark at that commercial. He also does not like Oprah and barks at her a lot.

The funniest thing I've seen him watch was a program about bigfoot. Every time the "bigfoot" would walk across the screen, he would go crazy barking. He was really afraid of it.
He also loves to watch the fish in our aquarium (large cichlids) and constantly notices people and animals on my computer screen. He is such a weird little dog.
