It is very normal for humans to dream, and some owners say dogs also dream. Sometimes dogs make whimpering sounds while sleeping, and sometimes their bodies twitch a little. So, when pets show these signs, does it mean they are dreaming? Do dogs actually dream?

　　Scientists have studied this before. In fact, most reptiles do not dream; birds do dream, but most species only have short dreams; for various mammals, such as dogs, cats, horses, elephants, mice, hedgehogs, squirrels, etc., they do dream. Moreover, some mammals dream quite frequently. From this conclusion, we understand that mammals like dogs do in fact dream.

　　Like humans, puppies also experience joy, anger, sadness, and happiness during dreams, sometimes even acting out as if performing, and veterinarians share this view. One veterinarian said: “Maybe at night in a dream, it remembers experiences, so if it was punished during the day, it might cry at night, or if it fought with a dog during the day, it might be aggressive.”

　　Pets cannot talk, so even if they dream of something, they cannot clearly express it. But dogs show various signs while dreaming, such as making whining sounds, twitching limbs, sometimes drooling, sometimes breathing rapidly, etc. When pets show these symptoms, it is very likely they are dreaming.
