do dogs have nightmares

Yes, dogs do have nightmares. Like humans, dogs experience rapid eye movement (REM) sleep, during which dreaming occurs. Nightmares in dogs are unsettling dreams that can cause them to twitch, whimper, bark, or even appear disoriented upon waking. Dogs may show signs like soft distressed sounds, twitching, rapid breathing, growling, or barking during a nightmare. Nightmares may be more common in dogs that have experienced stress, trauma, or anxiety. Sometimes dogs also experience night terrors, which involve more intense vocalizations and body movements and happen during non-REM sleep phases. Owners should be cautious about waking a dog during a nightmare, as they might react aggressively out of confusion. It is best to let dogs wake up naturally and comfort them after they are awake if needed.
