Is my Dog Going Crazy?

Barking at nothing may be a frustrating and odd problem for some dog owners. However, truth is, most likely your dog is not going crazy nor is he seeing paranormal activities you are incapable of witnessing. If Rover is barking and you get up to check what all the big deal is about, only to find nothing, in reality there may be something our ears are simply unable to capture.

Equipped with ears capable of detecting frequencies between 40 to 60,000 Hertz, dogs are blessed with a state-of-the-art hearing system far superior to humans. Humans, on the other hand, are capable of hearing between 20 and 20,000 Hertz.. Frequencies humans are capable of hearing are often referred to as "sonic". Frequencies that are higher in pitch and not detectable by humans are known as "ultrasonic". Dogs are capable of hearing frequencies in this ultrasonic range and this includes the pips and blasts from a silent dog whistle to the small squeaks emitted by mice. This therefore, causes dogs at times to bark at noises in frequencies we cannot detect.

However, dogs do not bark only as a reaction to noises.Their other senses may also detect stimuli which may cause a big barking spell. Equipped about 220 million olfactory receptors in their noses, dogs are also blessed with a superior sense of smell especially when compared to humans to the mere 5-6 million receptors in people. Dogs have also been used to detect explosives, drugs and even bed bugs. It is not unusual, therefore, for a dog to smell a wild animal and then bark from frustration of not being able to get to it.

What May Be Causing Unexplained Barking?

So what is causing Rover to bark at repeatedly when there is nothing there? It is hard to say, if only we had the powerful ears and noses and the mind of a dog! We can however makes some assumptions at times. The following are some common causes for otherwise unexplained barking in dogs.

  • Wild Critters

One of my client's German Shepherd's was having odd barking spells in the evening. He used to seem to go crazy. And the owner's question "What is it?" seemed to be making it much worse as the dog went into a frenzy pacing and whining as if trying to explain something. The mystery was solved months later when they discovered to have a family of mice living right under the front deck and parts of the basement. Their dog was right and now that the mice have been exterminated, the dog is much calmer in the evenings.

  • Distant Noises

You may not hear noises from a distance but your dog does. It could be your neighbors just parked their car a few homes away from you or that another dog is barking from a distance. There are many noises that we cannot hear while our dogs can. Often, barriers such as doors and walls make it difficult for us to detect distant noises while dogs can hear them with little problems. Dogs often are even able to detect the origin of a sound; for survival purposes it is important to determine the exact location of a rabbit so to have a meal for the day!

  • Attention Barking

This is a totally different type of barking, but at times, dog owners believe the dog is barking for no reason. If your dog is looking at you and barking, chances are, he may be looking for attention. If your dog is an attention-seeking dog, he will love to see you notice him and make eye contact. If you talk to your dog or pet your dog too, you will further enforce this type of barking. Dogs that do not have much attention during the day may even appreciate negative attention. Scolding him is in his eyes may be much better than no attention at all!

  • Barrier Frustration Barking

If your dog detects exciting stimuli outside beyond the fence, your dog may engage in barrier frustration barking. Eager to get at what is at the other side of the fence, but unable to, barking is a way for the dog to manifest its dissatisfaction. The stimuli detected are not always detected by humans, the dog indeed may smell a female in heat or hear a dog barking a few feet away. This form of barking is "distance decreasing barking" in other words the dog wants the other stimuli to come closer and make contact but unable to do so, the dog gets frustrated. Territoriality, on the other hand, is distance-increasing barking, the dog wants to send the stimulus away. The stimulus in this case, is as well not always perceptible to humans.

  • Health Problem

It never hurts to have a veterinarian check a dog exhibiting unexplained barking. At times, pain may cause a dog to bark but there are also other explanations. Senior dogs at times engage in aimless pacing and unexplained barking as they roam the house disoriented. This may be a sign of canine dementia which can be relieved with medications.

There are many other triggers that may cause dogs to bark. Therefore, your dog is not seeing ghosts but is most likely detecting something your senses cannot detect. This is a good reason why humans appreciated the company of dogs eons ago; the dogs were fast to set the alarm when threatening animals were getting too close for comfort.

How to Reduce Unexplained Barking

Because at times it is hard to pinpoint the exact cause of barking, solving unexplained barking may pose some challenges. If your dog is barking for attention, the best course of action is to ignore the barking and pretend it is not happening. Make sure your dog is getting enough exercise, mental stimulation and all his needs are met.

At times, playing some white noise may help reduce barking. There are many CD's for dogs who need relaxation. A pheromone diffuser may be helpful if you recently rescued a dog and it is having a hard time adapting to new noises and smells. Dogs tend to bark less if allowed to stay in the home versus kept in the yard all day. Dogs are pack animals and thrive with human companionship. It is important to put some effort in determining why your dog is barking so to help reduce the barking in the first place. Going to the root of the problem is key.

If your dog is barking, try to listen and find out what is going on with your best friend; truth is, barking is one of his ways for communicating something might be amiss. Many people have scolded their dogs for barking only to find out they had a very reasonable excuse for doing so. Just the other day, my male Rottie was whining and I could not figure out why...I went in the kitchen only to find out water was pouring out from the pot on the stove. My female Rottie instead alerts me when some nasty bug makes its way in our home. She will announce its presence with the most disgusted yelp. Truth is, our dogs are talking, are you listening? It may be worth it!

Questions & Answers

  • My puppy barks every time I leave my apartment. He does this even if I have been home all day. Why is he barking like this?

    Your puppy sees you as part of his social group. You are his family. It sounds like isolation barking. This can become problematic as he grows up and may develop into separation anxiety. Try to get him desensitized to brief departures and leave him with some goodies to stay occupied (stuffed Kong toy).

  • I have five dogs, and one out of the five will randomly bark loudly and only once. Why is my dog doing this?

    It's most likely now and then there's some stimulus that triggers the barking. If you observe your dogs, you may notice what triggers this pattern of barking. When several dogs are together, there is often one who is more alert.

  • Why is my dog barking at one spot in the yard and digging and nothing is there?

    We may assume there is nothing because we are limited with our senses. There are chances your dog smells traces of some animal or perhaps hears the ultrasonic sounds produced by some critters living underground.

      I took my puppy from a dog foster home about a year ago. I love him to bits; he has a great personality, and I feel that he loves our family so much. BUT he barks and whines A LOT… So, leaving home is always a challenge for us. My husband and I were thinking about taking him to 'doggy school', but then again, it’s extremely expensive, and the nearest 'doggy school' is far away from us. Maybe you have some advice? THANK YOU!!!!

      Could be there are critters in your home, which are common this time of the year. Dogs can sense them, while we often don't.

      I know that dogs have super-sensitive hearing powers, much much more sensitive to humans', that's why whenever they hear just a distant rustling from outside they bark and bark -- good for guarding your property, needless to say.

      That's why when my dog hears loud sounds (like booming sounds from a firecracker) she runs aimlessly and howls pitifully. In the end she hides under a table or even inside my bathroom. For us humans it's just a normal volume but to a dog it's an aural torture.

      Great hub you've got. Voted up, interesting/useful and shared.

      That is so cute. I know a little dog that used to do stupid funny stuff but we never thought to put a curtain up. Thanks for the idea.

      I used to own a Chow that would bark incessantly at the TV when it was turned off. It took me a while to realize he was actually barking at his reflection. (He was NOT a smart dog.) We eventually had to resort to putting a curtain across the TV when not in use.

      A very useful hub. My Dog will sometimes just seemingly bark at nothing, but as you say there our hearing is poor compared to a dog's. So its something worth bearing in mind. Thanks and Voted up etc.

      My pooch is forever barking. He is either hungry, wants to play, sees someone walking by, sees another dog, or wants loose because he smells a female dog in heat?

      There is always a reason for the barking. We only have to find out what the reason is.

      Just because there aren't any female dogs in the vicinity does not mean that he cannot smell her pheromones. A male dog can scent a female in heat within a 5 mile radius. Drake gets all jittery and bouncy when there is one around.

      Yes, that's a possibility as well. I've even noticed them barking when they hear noises especially fireworks. We may not be able to hear the ones at a distance but they can.

      Also dogs have better vision then us. They can see things at a greater distance that we can't see with our limited range. So, Fido might be barking at a rodent in bush 50 yards away!

      Great hub. My dog does bark at the neighbors, and sometimes it takes me a while to figure out which neighbor is out and about at the time. He has a very loud bark and it does startle me when he starts.

      Thanks for this wonderful hub, it's got some great information and I'm surely going to pass it on to my neighbor.

      Great hub. I didn't realize the hearing sense of the dog, though I know it's definitely better than mine. Funny how it can be nice and quiet in the house and I'm concentrating on something, then wham, the barking begins and can give me a jump from the sudden bark! I imagine my dog thinks it's funny, but she gets me every time, and sometimes it's all the dogs at once. But they are barking at something, which I sure didn't hear-I was enjoying the peace and quiet-then I let them out and sometimes they continue and sometimes they run out and stop with a quizzical look on their face. Never a dull moment.
