AnswerpoDogs don't "sleep". They'll just nap... That's why it's easy to wake a "sleeping dog". And if they don't literally sleep, they can keep their eyes open while "sleeping"It's actually normal for a dog to be sleeping with its eyes open, that means it's had a long day, or it's not sleeping, just staring at something.
Some fish do not have eyelids, so they cannot close their eyes when they sleep. However, some species of fish may exhibit a form of rest where they remain still or hide in a safe spot without closing their eyes.
watching because its like that when you watch your eyes start to like close and you put energy to your eyes to leave them open like more better than closing them and the energy burns more fat than sleeping. thanks. by:yashvi kumar
