If you’re wondering, “Why is my dog growling at nothing at night?” this blog will help you understand the root causes and how you can effectively calm your nighttime growler.

STOP GROWLING: FREE REACTIVITY CLASS

Now, it might seem like your dog growls at nothing, but there could be more to it than meets the eye.

Is your dog feeling stressed? Are they in pain? Or maybe there’s something outside that’s got them on alert?

It’s time to figure out what’s really going on and how you can help them (and yourself) get a better night’s sleep.

Let’s dive in. 

Key Takeaways

  • Why Your Dog Growls at Night: Your furry friend might be growling, whining, or barking due to various reasons. They could be feeling scared or anxious, especially in a new environment or if they’re a young pup. Their senses are super sharp, so they might be reacting to sounds or smells we can’t even detect. They might be uncomfortable, maybe their bed isn’t cozy enough or they’re feeling under the weather. Or, they could simply be feeling lonely or protective of their territory.
  • How to Help Your Dog Sleep Soundly: Make sure your dog has a comfy bed and a safe, quiet space to sleep. If they’re new to your home, let them sleep near you at first to feel secure. Show them you’re the boss by setting clear rules and boundaries – this can actually make them feel less anxious. If they’re barking at every little noise, training techniques can help them relax and feel less alert.
  • Become Your Dog’s Loving Leader: Dogs are pack animals and need a leader to feel safe. Learn the Five Golden Rules of dog training to establish yourself as the leader and help your dog feel more secure and relaxed.

Understanding Dog Growling At Night

First of all, the term “growling” is what we’re using in this blog. However, the sounds your dog makes go beyond growling. It could be a whine, a snort, a whimper of discomfort, or a woof escalating to a snarl. 

We’re going to look at all these sounds and why your dog is making them. 

What I suggest we do at the very start is to understand why your dog growls.

What Does My Dog Want If They’re Growling?

As humans, we use a lot of words to communicate many things. There are also feelings and expressions we show through sounds: we sigh, we go “tut tut,” and even say “Huh?”

These sounds are such a big part of our communication, we instantly understand what they mean. 

Just like us, dogs use sounds to communicate their feelings and needs. A sigh, a whimper, or a growl all have different meanings. So, what are they trying to tell you when they have nighttime growling?

Common Reasons Why Dogs Growl at Night

Reason #1: Your Dog Growls Because Of Fear And Anxiety

Your dog, like people, can feel nervous and scared.

A young puppy, or a dog that’s recently left their pack might feel particularly unsafe in a new home, especially at night when everything is quiet and unfamiliar.

They might whimper, bark, or even growl at the slightest sound. Most of the time, there’s nothing there but the wind rustling the leaves outside.

Your dog’s behavior is similar to separation anxiety in humans, where the fear of being alone can trigger feelings of insecurity and panic.

A nervous dog might overreact to any touch or loud noises, like a jumpy person who startles easily. This is because their heightened anxiety puts them in a state of constant alertness. An anxious dog is more sensitive to their surroundings!

Luckily, there are many ways to help your dog feel more secure and relaxed, which in turn can help both of you get a good night’s sleep.

After all, a good night’s rest can do wonders for dog and owner, reducing stress, improving mood, and promoting overall well-being.

Reason #2: Heightened Senses

The second reason why your dog suddenly starts growling at night is heightened sensitivity to smell, sights, and sound.

Some dogs seem to go on full alert when they sleep, their ears half-cocked, picking up even the faintest noise.. Their hearing and sense of smell are far superior to ours, so even in the dark, they haven’t lost their primary senses. They’re incredibly sensitive and can react to sounds and smells we can’t even perceive.

FREE REACTIVITY MASTERCLASS

For example, I once dropped a tiny piece of orange with a worm in it while I was outside. Later that night, my dogs went out for their last bathroom break and found it. They could identify that tiny piece of fruit or the scent of my fingers from a considerable distance. 

A dog’s sense of smell and sound are truly remarkable!

So, when we say they’re growling at nothing, it’s not entirely accurate.

Most dogs are actually hearing or smelling something, and they’re simply asking, “What’s that?” In a dog pack, just like in a wolf pack, there are always some dogs who are like alarm sounders. These dogs, often the more nervous ones, are more alert and have better hearing.

It’s like having a nervous dog with heightened senses in the dark who’s always listening for everything. They might make a noise like “ruff,” and that’s all it is. It’s like they’re saying, “What’s that? Wake up, guys? Can somebody identify that smell?”

It could be anything from a neighbor cooking dinner, a small rodent scurrying around outside, or the wind blowing.

Reason #3: Underlying Medical Issues and Feeling Unwell

Sometimes, your dog starts growling at night because they’re not feeling well. This could be physical pain or even emotional distress. It’s important to remember that dogs have feelings just like us.

Imagine being given a thin blanket on a cold concrete floor as a bed. You wouldn’t feel safe, loved, or comfortable. You wouldn’t get a peaceful night’s sleep, and every little noise would wake you up. 

It’s the same for your dog. A comfortable bed can make a big difference to their well-being and sleep, especially if they have health concerns.

Reason #4: Discomfort

Your dog’s environment plays a big role in their comfort, and therefore, their sleep. If you live in a cold climate, a thick, cozy bed is essential. In a hot climate, your dog might prefer a cool marble floor.

Consider your dog’s breed, too. A husky in Arizona will be hot most of the time, while a Vizsla in Alaska will likely be cold. Think about what your dog needs to stay comfortable temperature-wise.

Also, consider their emotional needs. Your pet naturally prefers den-like spaces with only one entrance to guard so they can relax. Just as you wouldn’t feel safe sleeping in the middle of a warehouse, your dog might feel more secure in a smaller space like a corner of a room, a crate, or a kennel.

Crates can be especially comforting for your dog because they mimic a den, especially with a blanket draped over the top. They offer a sense of security and protection from drafts.

I always make sure my dogs are warm at night, either with blankets or a little jacket if they get cold. We even leave the fire on sometimes for extra warmth. These small things can make a huge difference to your dog’s comfort and sleep.

When your dog is free of physical discomfort, their nighttime growling lessens, too.

Reason #5: Separation Anxiety

If you’ve recently brought a dog home from their pack, they might feel lonely and insecure. Letting them sleep in your bedroom for a week or two, then gradually moving them out, can help them adjust. While I don’t recommend letting your dog in your bed, having them closer to you can make them feel safer.

Think about where your dog sleeps in the house. Keeping them in a kennel far from the house can feel like isolation for a pack animal who craves companionship. Your dog wants to be close to you, so try to accommodate that.

Reason #6: Territorial Behavior

Dogs are naturally territorial, and this can lead to nighttime growling. Even inside the house, they might hear or smell something outside that they feel is intruding on their territory.

My dog Willow had different growls for the postman, a cat, a deer, or a rat. She even had specific barks for intruders, dinnertime, or when she wanted me to check something out. By learning her language, we understood what she was trying to communicate.

Try to learn your dog’s language too. They might be growling because they smell something outside, and that’s perfectly normal. The more you show them they don’t need to react, the more relaxed they’ll become.

Environmental factors like ambient noise, low light, or any changes in the environment can make dogs more vigilant. It could be a windy night, rustling leaves, or even a twig brushing against a window. All these things can contribute to nighttime growling. We need to help our dogs feel safe and relaxed.

Sometimes, our dogs know there’s no danger because we’re there and have reassured them, but they still feel the need to stay alert for our sake. We need to show them it’s okay to relax and let us take charge. It’s our responsibility to help them feel safe and secure.

Reason #7: You Haven’t Shown Them You’re the Pack Leader

Our furry friends are programmed to look for a pack leader. Your dog’s natural instinct is to search for leadership in the name of survival. If your dog doesn’t see leadership in place, they will assume the role of the leader. 

And for your dog, leadership means guarding and protecting you and the property. This is why they’re always agitated, anxious, and protective.

“Doggy Dan, are you saying my dog doesn’t see me as their leader even if I walk and feed them?” 

That is correct. Dog psychology works differently. You have to follow certain rules to help your dogs understand “Hey, I’m in charge here. You can calm down.” 

I’ve taught these rules — I call them The Five Golden Rules — to thousands of dog owners, and they work like magic to change dog behavior. Once these rules are in place, training becomes much easier.

Strategies for Controlling Your Dog’s Growling Behavior: Tips From a Professional Dog Trainer

Strategy #1: Create A Safe Space Where They Can Retreat And Feel Safe

Creating a safe and comfortable space for your dog to sleep should be your top priority. Many dogs find comfort in crates. If you can train your dog to use one, leave the door open but drape a blanket over the top and place another inside to make it cozy.

Choose a quiet spot away from drafts and noise, like doors or windows. A good bed, perhaps with a thick mattress, a blanket, and a pillow, can make all the difference. My dogs adore their faux sheepskin beds — they snuggle right in!

Strategy #2: Train Dogs To Be Calm

Consistent training can help if your dog growls because they think it’s expected of them. Teaching your dog to relax is a valuable skill, especially in multi-dog households. My dogs have learned to switch off once they’re inside the house.

They lie down and relax, knowing they’re safe indoors. You can achieve the same by teaching your dog to be calm and quiet, rewarding good behavior with positive reinforcement, and ignoring unnecessary growling.

Strategy #3: Avoid Overfeeding Your Canine Companion At Night

I only feed my dogs in the morning so they’re not full before bed. By bedtime, they get a small treat or chew, which helps them relax and settle down. A long walk before bed can also tire them out which makes bedtime easier for everyone.

Strategy #4: Seek Professional Help

If the growling persists, or if there are any signs of illness, consult your vet. Your dog might be growling due to pain, which could be caused by anything from an abscess to a broken nail.

If you’ve tried everything and the growling continues, consider consulting an animal behaviorist. They have extensive experience with these issues and can offer tailored advice. Some dogs, especially intelligent breeds like sheepdogs, might growl for attention, and a behaviorist can help you address that.

Additional Tip: Observing Your Dog’s Body Language While They Growl

Observing their body language is the first step. Dogs communicate a lot through their body.

Look at their ears: are they pinned back in fear or alertly forward?

Is their tail tucked under or held high?

Are their eyes focused or darting?

Do you see bared teeth?

What about their posture — crouched, stiff, or backing away? These signals can reveal how your dog is feeling.

Next, notice when and where aggressive dog growling happens.

Does it occur at a specific time each night? In a particular room or location? For example, if the growling always happens near a window at the same time, it could be due to an animal outside or distant sounds you can’t hear.

Just started the dog calming course and from day one I’m seeing positive changes in my recently adopted rescue dog. He’s responding very well to me as Pack Leader and today a walk on the moor with other dogs about was much more relaxed. A long way to go but I expect daily progress from now on

I haven’t moved past the 1st lesson but I have been very diligent with my 2 rescue dogs - I’ve had 1 for 2 1/2 yrs the other only 4 weeks - my old rescue died 6 months ago aged 17yrs (I adopted him when he was 9 months old) Barking at the front fence and terrifying people has been my issue - while on walks they are the friendliest dogs I have been able to make myself fully available to them as I only work 2 night shifts fortnightly I have consistently gone out when they bark and say ‘thank you’ I’m all good! This week I included one of my other commands that I use when I feed them - I put their food bowls down and say stay - when I’m ready I say ‘come’ and they eagerly run to their bowls - this week I’ve included saying ‘thank you - come’ when they bark and they are now coming to me straight away Barking is lessening substantially but not yet ceased - I see it on the horizon I’m looking forward to moving onto the next lesson soon

Great. Change my mindset. Don't anthropomorphise the dog. They adopted us. I see the change in my over anxious young dog. I've tried quite a few other training methods in person and online BUT this one gets results. Positive results, tangible results. I needed results to help not only my dog and I but my husband and other people and dogs we meet in public places. Thanks Dan.

So far, so good! We started the Calming Dog a few weeks ago and while we humans have not been perfect at it, we are seeing differences in our dog. He is an incredibly reactive and protective dog, so the changes we have had to date are a huge blessing. I'm impressed at the approach, the actual simplicity of it combined with the science of dog behavior. Thank you, Doggy Dan and team!

Ridley is my 4th dog. After listening to and learning from Doggy Dan, I was happy to see that I did pretty well with my first 3 dogs while raising my kids and having my husband with me. Not perfect - but pretty good! Now I am raising a new dog by myself, and I feel like I'm not doing this really "alone." I really am so happy with all the information Dan has offered... and all his techniques work well!!

Two months ago I adopted a 7 year old Morkie, a very nervous but loving little fellow. I tried several different training techniques and even purchased a program that was lengthy and very time consuming before I discovered Doggy Dan. I've been using his program for two weeks and am astounded by the change in my Dexter. He is calmer, more obedient and friendlier to others than I imagined possible. Dan's training is concise. It differs from others I found, Dan trains you to become the leader of your pack through a dog's perspective. I like that the training is specific yet compassionate. This is a program that works if you are consistent. Thanks Doggy Dan!

Susie in the UK. I am only 10 days in but took in a 9 yr old emergency rescue from Romania who had been in kennels for 6 years and then had 3 failed foster placements in the UK. Luca is a big powerful mixed breed with huge stress and anxiety and very reactive, he bounded into my home and took over - aggressive with my 2 others, and visitors and pulling and pushing on walks. I thought I couldn't handle him but saw an advert for Doggy Dan on line and signed up - we've had a wonderful turnaround and he is finally decompressing, being polite with my dogs and responds excellently to the time-out if reactive with guests. Walks are much better and all 5 rules are in place. I believe he will continue to improve but only if I remain 100% consistent with him for the rest of his life. He is 9 years old and deserves a happy old age being loved and looked after with no further upsets in his life so fingers and toes are crossed for him

I started. The course 3/4 weeks ago. As Dan says you have to work on things if you get stuck. I have a Staffordshire x cane corso who is now six months old. She is very intelligent but sometimes she just doesn’t listen. Doing the five codes I’m finding it’s going pretty well except trying to get her calm so I am persevering with it again with my own space. I have a trainer call shortly which I will ask for advice on this. It’s great also that you can ask anything you’re not sure of on line. It’s so great to have someone there to help. I’m looking forward to having a relaxed girl instead of hyper most of the time as she gets so excited about almost everything. I would truly recommend doggy Dan and just wished I would have come across him much earlier. Thanks again for everything so far.

This program is amazing!. We have a VERY reactive rescue dog that has bitten his previous owner and as well, myself 3x and my husband 4 x's. He had never been around people or other animals, and had never been walked on a leash. (in fact never run off-leash either, just tied to the front steps). We began with traditional treat-based training with a professional, but the progress was frustrating. A reactive dog does not want treats; it wants comfort. With the 5 Golden Rules and and some of the other training we have received with our subscription, in just 3 weeks, we can let him off leash at the dog park, he has not growled at any stranger, and he has not attacked any other animals. He is still a work in progress, but we see progress!!!! He has become a cuddly, sweet dog and for a greyhound, he even has recall! This program is amazing to say the least. We were at our wits end, but now we have hope.

Okay, he says it’s not magic, but the results and the peace in so little time with so little effort sure feels like magic! My 11 month old pup was a 60lb highly reactive, very loud disaster waiting to happen. Now we are both calm, the house is quiet and I don’t live in absolute fear of his reactivity towards others. There’s always still work/training to do of course, but wow are we in a much better place to get on with that!

We have an 8 month old Goldendoodle who has fear issues outside the home and gets easily overwhelmed going into panic/flee mode if several triggers coincide (people, loud dog barking and noises like motorcycles/construction). So pleased to find Doggy Dan and seeing positive changes after just two weeks. Feeding time is calm after using the gesture eating and "thank you" when he barks works a treat. I realized I'm babying my dog too much and trying to be his best pal instead of a leader so I'm working hard on that. We've changed to the no pull harness and love that. Doggy Dans video clips really help bring the philosophy together and I love his attitude. He is calm, clear, firm but so kind and loving with dogs and very down to earth and relatable. I've got great help too from the AI coach and the daily emails and videos help keep us on track and feeling positive. We've still got a mountain to climb with our pup but I finally feel hopeful and supported. We'd tried trainers, behavior specialists and all sorts before finding Doggy Dan and this is by far our best investment. Can't recommend you trying this highly enough. Photo of our boy.
