Do dogs like TV left on?
For pups with separation anxiety, the noise can actually help them feel secure. The idea behind this is that you train your furry friend to think of the TV as a safety cue, as well as something that doesn't remind them of you.
It can help to make your dog acquainted with different stimuli which makes them less likely react in an anxious or startled way. If your dog has separation anxiety, you might find that pet TV shows help to give them something to focus on so they are less anxious.
Action: Action-packed movies and TV shows can be good for your dog, too. Watching them in a safe space with their pet parent can desensitize dogs to the loud sounds or sudden movements on screen when they encounter similar actions in real life, Millan says. Just be gentle with the volume—dogs have a great hearing.
