I think dogs dream like humans while they are asleep. I wonder what they dream about.

I wonder what good dreams are for them. Maybe about a squirrel, a treat, or a walk. But what about their nightmares? Do they dream about getting lost, do they worry about their family? Do they even think about those things? Or do they worry about not seeing the next dog that walks by or not chasing that squirrel? Humans sometimes dream about their worries, do dogs do that as well? Do dogs have worries?

I wonder what dogs dream about…if they dream at all.
