Dog Barking

All dog owners around the world have grown accustomed to an occasional bark here and there. For some, though, their dogs seem to be barking at absolutely nothing. This constant barking without cause becomes a little frustrating or unsettling if you rely on them to alert you about potential danger lurking nearby.

Even though a dog’s barking feels random, there is usually a reason for it, whether you notice it or not. Barking is a dog’s way of communicating with you as well as their surroundings. So if you listen more closely, you might be able to figure out what exactly has them riled up.

The 6 Reasons Dogs Bark at Nothing

Dogs bark for so many different reasons that it is hard to say exactly what is setting them off. Try to understand that this is your dog trying to communicate with you, even if you do not know why.

1. They Sense Something You Don’t

Dogs have more sensitive hearing and smell than us. Dogs are capable of hearing higher frequencies, seeing in lower light, and picking up on subtle smells. Just because you do not see, hear, or smell something doesn’t mean that they don’t exist. Of course, this doesn’t always mean that you’re in danger, but it just means that they may have sensed something in the distance and they’re unsure about what it is.


2. They Want Attention

If you acknowledge your dog every time they go on a barking spree, they may start to associate your attention with making noise. Dogs wanting attention may sometimes look you directly in the eyes while they bark. To discourage this behavior, you should avoid reinforcing the barking by giving attention immediately and avoiding eye contact. Try to avoid speaking to them as well. Even if you simply tell them to be quiet, they are still feeding off every bit of attention they can get.

3. They’re Bored

It feels like some dogs bark just because they like the sound of their own voice. A bored pup is much more likely to bark repeatedly if they have nothing else to stimulate them. Your best option is to take them for a walk and get rid of some of their pent-up energy.


4. Something Has Scared Them

Dogs have many ways to respond to stress or fear, and barking is one of them. If a dog is scared or stressed, they could be barking to increase distance from or deter whatever has them frightened. If you know they’re scared or anxious, then it’s okay to comfort them until they calm down.

5. They’re Being Territorial

It doesn’t matter if a human is visiting or a squirrel is running through the yard. Dogs are naturally territorial about areas they consider part of their home or resources, and loud barking is your furry friend’s way of telling others to stay away. Territorial barking is usually loud and sounds a little more authoritative. It helps to train them to keep their voices down whenever you have guests over.


6. Something Exciting Is Happening

An excited bark is one that we don’t usually mind as much. Dogs bark when they’re feeling excited or highly aroused. They could have a barking fit whenever they know they’re about to go for a walk, play outside, or see a fellow canine friend. Don’t punish your dogs when they’re feeling happy. This is one way dogs express excitement vocally, and they may have difficulty controlling it without training.

How to Reduce Unexplained Dog Barking

It’s not always easy to pinpoint the cause of excessive barking. If it feels like they’re doing it for attention, the best way to combat it is to ignore them and teach them that their behavior won’t be rewarded. However, it isn’t always this easy.

Many times, we have to do a little trial-and-error to figure out a dog’s behavior. Your first action should be to take them outside or have a play session with them to burn off some of their energy. It’s possible that your dog is getting enough physical and mental stimulation. Keeping them entertained is one helpful way to tire them out.

Some dogs have anxiety-related barking. If you’ve tried increasing their exercise and enrichment and it didn’t work, put on some relaxing music for your dog. This may help mask outside noises and promote relaxation for some dogs. There are plenty of calming music playlists for dogs that are only a quick Google search away. If nothing else worked, it is always best to turn to a vet for help and advice.

Final Thoughts

When we buy a dog, we expect that they are going to bark a little bit. It’s only when the barking gets out of hand that we start to become frustrated with their loud behavior. Try to be patient and learn what is triggering them. Once you’ve figured it out, it makes it a lot easier to calm them down and manage or redirect their behavior.
