![]() ![]() But sometimes, watching a dog dream can be indicative of his breed. How Can We Tell a Dog is Dreaming?ĭogs often bark or twitch their legs during REM sleep, the Sleep Foundation reports. We know that they are in fact dreaming and their dreams are connected to actual experiences.”īecause rats are intellectually less complex than dogs and cats, researchers make the assumption dogs and cats dream just as rats do. “We looked at the firing patterns of a collection of individual cells to determine the content of rats’ dreams. “No one knew for certain that animals dreamed the way we do, which can involve replaying events or at least components of events that occurred while we were awake,” said Matthew Wilson of MIT’s Center for Learning and Memory. They found that the brain activity was the same as when the rats were running, leading researchers to conclude that the rats were dreaming about the maze they ran earlier that day. ![]() Later they measured the brain activity while they were in rapid-eye movement sleep, the sleep cycle in which humans experience dreams. How Do We Know Dogs Dream?īack in 2001, Researchers at MIT trained rats to run a maze and measured their brain activity. Scientists think so-in fact, they believe that dogs not only dream as we do, but also that they dream similarly to us, meaning that they replay moments from their day while they’re fast asleep. Your dog is fast asleep, when suddenly he starts whimpering, moving his legs or tail, or engaging in some other odd behavior.
