7 Reasons Why Dogs Whimper in Their Sleep

Among many other human-like characteristics sleepy whimpering is the one that makes you wonder whether dogs have such vivid dreams as we do – probably even more so.

A dog whimpering in sleep is just verbal communication on a subconscious level.

Except for dreaming there are a few other things that might trigger this not-so-odd canine behavior.

With the help of this article, you can check what category your dogs falls under and if the whimpering is concerning or just super cute.

Causes for Dog Whimpering in Sleep

The main cause why dogs whimper in their sleep is dreaming but seizures or pain should be ruled out as possible causes. When the dog is technically awake but sleepy, you might hear whimpering due to boredom or anxiety.

Dogs never whine and whimper in their sleep without a cause.

The reason might not be noticeable or relevant to the dog’s health and well-being, but it’s still there. Thankfully, most cases are nothing to worry about.

Whimpering is frequently accompanied by twitching and while being a seemingly benign issue it sometimes requires closer attention because some of the theories we are going to describe might come as a surprise.

Dreaming

Dogs spend almost half of the day sleeping, and puppies and elderly canines even more.

The phases of a dog’s sleeping cycle are very similar to human ones so you might expect your dog to go through deep sleep and the REM (Rapid Eye Movement) phase.

Whimpering while sleeping happens during the REM phase because this is the period when they dream.

The phase repeats every 30 minutes for smaller dogs and every 45 minutes for large breeds.

During this time smaller pups dream for a couple of minutes and larger ones for 5-10 minutes.

My Rottweiler puppy is sleeping and often whimpering which is pretty common for pups when dreaming.

Whimpering, crying, and even growling is quite normal when there is a peak in brain activity.

Even though it may appear violent or uncomfortable it doesn’t necessarily mean that your dog is having a nightmare.

One can never be sure what our beloved furry friends are dreaming about.

We can only guess they are reliving some casual situations that happened throughout the day.

Even if it’s a scary dream the activity should go uninterrupted because dreaming contributes to healthy mental activity.

An average-sized dog has his first dream approximately 20 minutes after falling asleep.

When the dream starts the breathing becomes irregular and shallow, the muscles start to twitch and the eyes move fast behind the closed eyelids.

Puppy Behavior

Whimpering and whining in sleep is an expected puppy behavior.

Puppies are loudest the first week or two after they get separated from their mothers and littermates.

The cause of the whimpering is the need for attention and company.

Puppies can also get especially twitchy in their sleep – a lot more than adult dogs.

Their underdeveloped brain stem responsible for sending muscle-relax signals is less efficient in keeping their bodies calm.

Excessive twitching and puppy whimpering go away on their own eventually.

I know it’s hard to ignore the whining but you should refrain from reacting.

Comforting your puppies when they are showing this behavior positively reinforces them to keep whining anytime they need attention, thus the problem just becomes more irritating.

Seizure Episodes

Twitching and vocalizing while sleeping can be symptoms of seizures and other disorders of the nervous system.

While the type of whimpering can’t help you distinguish dreaming from seizures, the intensity of twitching can.

Kicking and paddling legs in seizing dogs are a lot more rigid and stiffer and with that, the movements appear a lot more violent.

Some dogs defecate and urinate while experiencing a sleeping seizure which is rarely a case in dreaming dogs.

After a seizure, the animals seem disoriented and tend to breathe hard and drool a lot.

If you are suspecting that seizure episodes are the problem for your dog whimpering in sleep, talk to your veterinarian as soon as possible.

Painful Medical Issues or Discomfort

Pain causes dogs to whine obsessively.

When older dogs with chronic joint pain or other dogs with any sort of painful condition lay down against a surface putting extra pressure on the point of pain they whimper in their sleep.

Older painful whimpers are seen a lot more because more than one joint is affected and the illness is vastly progressed.

It’s very hard for a dog in pain to have a good night’s sleep and get the rest he needs and deserves.

When you think there is a chance that pain is the reason for your dog whimpering in sleep take him to the vet for a thorough check-up.

Rule out pain as a possible cause before you continue to investigate other reasons for whimpering in sleep.

One of the most uncomfortable health problems in dogs is bloat.

Dogs get bloated for many reasons – bad food, suboptimal feeding schedule, and foreign bodies can all contribute to excessive gas accumulation.

Some dogs are intolerant to allergic to certain types of food and can get bloated very quickly.

When the gas builds up to a point where the stomach and intestines cannot be distended any further the discomfort is unbearable.

A bloating dog will have a hard time sleeping, especially if he lies directly on the abdomen.

The condition is very serious and can turn into a disaster very quickly.

Bloat in dogs is an emergency that needs to be attended to as soon as possible.

Non-too-serious cases of bloat can also make your dog whimper from abdominal discomfort while sleeping.

Feeding dogs low-quality food or food that’s hard to digest just before bedtime can produce such symptoms.

If your dog has a problem digesting the food you can turn to a bland diet like cooked rice and boiled chicken or ask your vet about other possible feeding options.

Boredom

All dogs need their regular daily exercise to get enough physical and mental engagement and stimulation.

Sadly, many owners can’t meet their dog’s needs for sufficient exercise.

Even house dogs must enjoy at least 30 minutes of exercise (doesn’t always have to be waking, your dog can swim for exercise too).

Dog sleeps next to owner, possibly bored and whimpering seemingly in sleep even though the dog is awake.

It’s likely for your dog to get bored by his daily routines if you don’t take him out to play often enough.

Boredom can be expressed when everyone goes to sleep and the dog starts whining and whimpering for no obvious reason.

Some dogs express these emotions with their eyes closed so it may seem like they are sleeping, but actually, they are widely awake.

Once you start talking to your dog or let him out in the yard to run around the whimpering will stop so you will know what the problem was in the first place.

It’s needless to say that more frequent exercise routines will solve the problem when boredom is the cause.

Separation Anxiety (or any other type of anxiety)

Many dogs are overly connected with their owners and start whining when they get separated from them due to separation anxiety.

You are not letting your pup sleep in the same bed with you? – whining starts.

Separation anxiety is a common problem and instead of opting for medications right away, you should start training right away if you notice symptoms.

Separation isn’t the only reason for late-night whimpering, but also any other trigger (ex. storms) that makes your pet anxious and afraid.

Improper Training

Dogs can keep on whining and whimpering during the night throughout their whole lives if they haven’t been trained to stop.

Most dogs stop as they get older, but some don’t. Enrolling whimpery-dogs in behavioral classes early on can put an end to the problem.

Why is My Dog Crying at Night All of a Sudden?

Many of the reasons we described like dreams, loneliness, anxiety, storms, pain, discomfort, and fear can trigger your dog to start crying all of a sudden at night.

Although you can’t be sure what happened exactly with only one crying incident, closely observing repetitive episodes can give you an idea of what to suspect according to the symptoms we mentioned before.

Is My Dog Having a Bad Dream?

Bad dreams make people annoyed, distressed, fearful, and anxious once they are awake.

Unfortunately, there is no way to tell whether your dog had a bad dream or a regular dream if he whimpered, cried, or growled while sleeping.

Even when they wake up and you can sense anxiety and alertness in them, it’s not a guarantee that the dog was having a nightmare.

Should I Wake My Dog Up from a Bad Dream?

While many owners are tempted to wake their dogs up from what seems like a bad dream, it’s best if you just let your pet dream on.

Disrupting REM sleep can have serious mental consequences.

Also, if you touch your dog during an active dream he may involuntarily bite or scratch (my Rottie definitely never does but I have seen anxious dogs doing it).

The only time you can attempt to wake a dog up is when you are not sure if it’s a dream or a seizure that’s going on.

In this case instead of touching your dog call out his name loudly or drop an object on the floor.

If the dog wakes up right away it was just a dream and you need to start talking softly and reassure him that it was just a startle.

Not waking up after the loud commotion could mean it was seizures causing the involuntary noises and movements.

All in all, your dog’s whimpering may just be a good old dream.

However, when it comes to possible medical issues, you should consult your vet.

Thinking your half sleepy dog has some attention issues or boredom? You can start training at home right away!
