Dog sniffing! Who hasn’t encountered that situation where your dog is focused on a scent? While we humans use our eyes to make sense of the world around us, customers are sniffing. Using their noses is often even the highlight of their walks, if not dominating their entire day. This outdoor exercise is healthy and helps release excess energy. It also gives them the opportunity to engage with their natural instincts.
Today I invite you to understand in this article Why Dogs Love to Sniff.
Before we try to answer these questions, let’s first take a look at the dog’s sense of smell.
Smell: Dog’s Primary Sense
Just as we use vision as our main sense for understanding our environment, dogs use their noses. The way something smells gives dogs more information than the way something looks, feels, sounds, or tastes.
In fact, dogs obtain more detailed advice from aura than we can even imagine. Human noses and brains simply aren’t wired that way.
But for you to really realize the importance of smell in dogs, know that our canine friends have over 200 million scent cells and we humans have barely 5 million! This is how much flair our dogs have!
This is mainly due to the size of their olfactory membrane (otherwise known as Jacobson’s organ) which measures nearly 130 cm² against only 3 cm² for humans. This organ receives quantities of information allowing it to detect and identify the pheromones secreted, reflecting an emotional state. These molecules convey signals aimed at regulating social behavior (sexual, aggressive, etc.). A dog can thus feel fear in his master even if he tries to hide it. The animal can also find its master’s clothing among a hundred others. Thanks to its extremely powerful sense of smell, the dog provides invaluable assistance in the search for explosives, narcotics, and missing persons as well as in the detection of diseases such as cancer, stroke, or diabetes.
Of course, there are exceptions
Indeed, gratitude to his feeling of smell in which he can have blind confidence, the dog will be able to detect serenity, enthusiasm, or on the contrary mistrust or fear of others. He will then adapt his attitude according to the information he has detected.
Let’s take a concrete example, when we say that dogs do not like going to the vet very much, it is not only because they remember bites, operations, or stitches, no, it’s not. is mainly because they smell the scent messages of fear and stress left by other dogs (through the filling ).back to menu ↑
About Your Dog’s Nose
What makes a dog’s sense of smell so effective?
The nose of your canine friend is designed to sniff and is more powerful than ours.
His structure is the secret to its amazing ability to detect, and understand, smells.
A dog’s nasal cavity
She is divided into two separate chambers and opens into two nostrils, or nares, that can wiggle independently and that can take in smells separately.
As a dog sniffs
Particles and compounds are trapped in the nasal cavity by mucus while scent receptors process them.
Scent particles are also trapped on the moist exterior of the nose. Some of the inhaled air goes to olfactory analysis and some of it goes to the lungs so your dog can breathe!
As a dog exhales
New odors enter the nose through the slits in their nose, to keep a steady stream of odors flowing.
Depending on breed
The ability of the dog to detect scents varies with long-nosed dogs able to distinguish scents better than the short-faced ones.
Each dog nose is unique
With its own distinct nostril shape and pattern of ridges and dimples. A canine nose print is as unique as a human fingerprint.
Dogs can tell from sniffing a tree or lamppost when a dog has passed, who it is and what status they have – male/female, top dog or not.
Dogs do not appear to distinguish between the regions of the human body which they sniff. Your armpits, to your dog, smell very similar to your feet!
A diet that is higher in fat and lowers in protein than the typical dog food is thought to be beneficial to the dog’s scent-detecting ability, though it is only dogs who work as scent-detection dogs that may need to alter their nutrition.
Aromas can affect dogs. Lavender, for instance, calms them down and reduces barking whereas rosemary increases it.
Researchers found that smells are taken one at a time into separate chambers within this olfactory recess and that contributes to the fine-tuned process of identifying individual scents in the environment. You may not be able to smell the leftover cheese from a long ago pizza on the sidewalk or that another dog had sat in a particular spot, but your dog would be able to sniff out those details.
Dogs can distinguish the scent of individuals, both dogs, and people. They can tell the difference between individual family members, even identical twins, purely by smell.back to menu ↑
Why do dogs sniff people?
When dogs sniff people they are gaining all sorts of information about us.
They know if we are familiar or a stranger, which scents we have attracted while we’ve been away, and also if we are experiencing changes in hormones, such as those that occur during pregnancy. Dogs may even know if we are experiencing illness or simply are in a bad mood.
Some dogs are politer than others in their sniffing techniques. Some will simply walk past a human, their noses gathering in the air surrounding us.
Others seem to need to get up close and personal, smelling our breath, our armpits, and even our crotches.
There is a lot that we don’t know about dogs and their ability to gain information from human scents. They may be able to detect cancer or to sniff out danger but this may take a lot of training to do so with any accuracy.
Dogs can also sniff us in full. In this case, that means they want to learn more about us from the smells we give off. It is important to let them do it. On the other hand, it is possible to train your dog not to sniff the private area of passers-by in the street, which can be a bit annoying for the passer-by as for the owner.back to menu ↑
Why Dogs sniff other dogs
The sense of smell is a dog’s primary sense. So, while your dog may recognize the shape of another dog by visual means, a lot more information can be gathered by sniffing them up close. Dogs tend to sniff where scents congregate and are dispersed.
This tends to be around the canine anogenital region. Hence, dogs like to sniff other’s dogs’ bottoms!
Rather than be embarrassed by this greeting, we should acknowledge that this is simply a dog’s way of saying hello. If your dog is being annoying to other dogs, then you need to take charge and direct their energy to more appropriate activities.
If your dog is frightened of other dogs being near them, then it may be worth seeking help from a behaviorist or trainer who can help with canine introductions.back to menu ↑
Do dogs use smell to communicate?
When two people meet, they evaluate body language, facial expressions, and tone of voice to quickly assess each other. With this information, they may shake hands or hug, share a casual verbal greeting, overflow with tears of joy, or they may totally ignore each other.
Dogs may not verbalize, shake hands, or hug like humans, but they do assess each other and gather lots of information from body language.
When two dogs meet they usually walk in circles while scrutinizing demeanor and posture. Are the ears back? Is the tail wagging? Are the hackles raised?
Dogs have an advantage over people in that they use their keen sense of smell, along with a visual assessment, to provide vital information about a new canine acquaintance.
Their acute olfactory senses enhance communication by using biochemical compounds emitted by dogs as the basis for chemical communication.back to menu ↑
Why does my dog sniff the soil?
Dogs tend to sniff the ground. It is a fact. However, some canines exhibit this behavior more than others.
Presence of animals smells of food, signs of anxiety or submission …
The reasons why a dog sniffs the ground vary from animal to animal and from situation to situation.
Wondering why your dog sniffs the ground all the time and what you can do about it?
Find out here the causes that may explain this behavior, the solutions to limit it as well as the symptoms of the disease to watch out for.
Anatomy, the first explanation
While humans explore their surroundings with their eyes, dogs do so with their noses.
Just as we use vision as the primary sense to understand the world around us, dogs use their sense of smell.
The smell gives dogs more information than looks, sounds, or tastes.
Think about the way the dogs greet each other. Information is transmitted by smell rather than barking or special gestures.
This difference between humans and dogs is mainly due to the exceptional potency of the truffle.
A dog’s nose contains up to 1 billion odor receptors while humans have only about 6 million.
Some dogs even have as many as 100 million or more odor receptors in their noses.
Among the strange behaviors of dogs is their tendency to sniff on the ground at the top of the list. But because everything is explained. This behavior also has its reasons.
Does your dog sniff the ground all the time? Here are the main possible reasons.
- To collect information
- Smells the food
- Because he smells of other animals
- He is anxious or nervous
- By submission
- To send a signal of appeasement
- To hunt
My dog sniffs the ground: when to see a vet?
There is a big difference between a dog that smells the ground during a walk and one that shows signs of breathing problems.
Make an appointment with your veterinarian if you notice that your dog:
- Makes an effort to breathe
- Breathe quickly
- Panting abnormally
- Breathe with your mouth open (without gasping)
- Has nostrils that widen when breathing
- Shows abnormal behavior or signs (lethargy, depression, tremors, vomiting, diarrhea, etc.)
Why You Should Let Your Pup Sniff on Their Promenade
Most dog owners recognize the importance of keeping their dogs mentally and physically enriched. Not only is it better for the dog’s general well being, but it can also help reduce the chances of problem behaviors arising as a result of boredom or frustration.
There are a whole host of puzzle toys available to let your dog try but, often, owners can overlook one of the most simple natural and enriching behaviors – sniffing.
By giving your dog more opportunities to use their powerful sense of smell, they will undoubtedly enjoy their walk more. They will also be more stimulated, gain more choice and freedom, and, ultimately, be more tired and relaxed.
When you take your pet for a walk in a new place, he will need to smell it and discover it by smell. It is a natural protective reflex and its only reliable means of discovery. He does the same when he meets someone for the first time. The dog likes to feel his legs in order to understand him and in particular to know if this person has animals. Thus, preventing a dog from discovering its surroundings through smell is as painful to it as if you had to discover yours blindfolded.
Realize that a dog needs to understand his surroundings, just like you as a human. Sniffing allows him to become aware of everything around him and see the dangers. Preventing it can cause a lot of stress for your dog, as some fearful mutts need reassurance by sniffing their surroundings. An animal that no longer knows where it lives will feel disoriented and lose its ability to socialize.
Should you let your dog sniff everything during the mall? What is he risking?
A healthy animal up to date with its vaccines is in principle unlikely to get sick, even if it sniffs feces such as urine and stool. However, be careful, because some bacteria are transmitted through this, despite a well-done vaccination.
Also, don’t confuse sniffing with licking or ingesting. Do not let your dog lick or eat any urine or stool, whether it is his own or anything you find during your wanderings. He can get sick or be contaminated by parasites!
On the other hand, do not hesitate to let your dog sniff his surroundings, it is a healthy act, completely natural, and which reassures him. If he has a tendency to follow leads and run away anywhere, keep him on a leash, but let him smell his surroundings to make it his own and allow him to discover it in peace. He will only be happier and more serene.
Letting your dog sniff gives him autonomy, a feeling of freedom that many doggies need to feel good because we must not forget that it is you who decides everything for your animal, its hours of meals, walks, needs, hugs, play, etc. This little freedom is therefore good for his well-being, so let your dog do it as long as he does not put himself in danger.
What to do if your dog is not sniffing?
It may happen that some dogs do not sniff their setting. Usually, it can be an anxiety disorder, transient, or long-lasting. Indeed, sniffing is normal and contributes to the good mood and well-being of the dog. It is therefore important to take the initiative and understand the reasons for this refusal.
First, try to reinstate the habit of sniffing. To do this, take a walk in the forest or in a quiet and protected place in which to scatter treats or croquettes. To eat them, your doggie will have to look for them and therefore use his sense of smell. In this context, most dogs regain their naturalness, even if it means reproducing the experience several times. However, if your pet does not sniff, consult the vet and let him know about your findings, as this behavior may be hiding a deeper disorder or illness.
However, take into account the peculiarities of your pet, because not all dogs sniff the same way. Indeed, certain races are naturally hunters and trackers; so they spend their time sniffing the ground. Others have a very flat nose which, on the contrary, does not allow them to breathe well the surrounding odors; these dogs usually do not sniff much, as they tire quickly.
Why is your dog not sniffing?
Does your dog no longer sniff when marching? Be aware that, in the canine breed, the loss of smell is generally only temporary. Whether in humans or animals, this disorder is defined by the term “anosmia“. The aging of the dog can have consequences on the performance of his sense of stench. To help him regain his abilities, you can scatter treats or kibbles on the ground, in the grass, hide them under objects and ask him to look for them. This little game will stimulate their sense of smell and promote their well-being.back to menu ↑
Why does the dog sniff the butts of his fellows?
Dogs often smell the bottoms of dogs they meet to greet each other. It might sound a little strange to us, but it is completely normal practice for a dog! Discover in this article this practice of our four-legged friends and why it is important to let your dog smell free.
By sniffing its congeners, the dog detects pheromones produced mainly in the anal and genital glands. These substances provide information on the identity of the transmitting dog: sex, age, physiological state (bitch in heat), mood, social position …
The chemical messages are also present in the marking (urine, stool) that males use more often than females. The deposition of secretions is also accompanied by visual signals (raising the paw more or less high, carrying the tail, etc.). By sniffing out the crotch of humans, dogs behave as they do with their peers and are therefore unaware of the embarrassment this can cause.
Give the dog some control over your route and over what breaks they want to take to sniff. Here are the reasons for it:
- This gives the dog important information about his environment.
- It gives the dog more control because he has a better understanding of the world.
- This helps mentally stimulate the dog
- It reduces the stress of the dog
- When a dog defecates, the anal gland leaves a unique scent
- Dogs recognize each other by this scent
- This scent gives information about the dog’s sex, identity, and mood
- The situation is often more calm and relaxed when the dogs can sniff each other
To feel is to greet
When they meet, dogs recognize each other and get to know each other by sniffing under the tail. Therefore, it is important to let them do it. Feel, calm the atmosphere and make the meeting more relaxed. When you are walking your dog and there is no danger of another dog approaching, let go of the ballast so that the dogs have enough room to turn around.
Feces are a calling card
A dog leaves a specific scent signature through his anal glands whenever he defecates. Dogs can recognize themselves by this scent that they spread by wiping their paws on the grass or wagging their tails.
By smelling the feces, a dog knows who has been there before him. And when they meet another dog, they like to sniff under the tail to find out who they are dealing with.back to menu ↑
You have to let your dog sniff everywhere
It is strongly recommended not to prevent your dog from collecting the information he gleans by scenting his fellows and the ground because this action stimulates him mentally. He needs it to develop fully and the lack of exchange and interaction could frustrate him. For people who are stressed or suffering from anxiety, sniffing is a great way to relax and socialize with their environment. Keeping a leash too short to slow down its olfactory exploration can be interpreted as a danger for the dog and encourage aggressive behavior in him.
Sniffing Can Make Your Dog Feel Better
Some dogs can become over-stimulated when they do high energy level activities, but harnessing your dog’s natural sniffing behavior is a calm and generally relaxing option.
A 2019 study published in the Applied Animal Behavior Science Journal even suggests that providing ample sniffing opportunities can make your dog feel more optimistic.1
Sniffing Can Make Your Dog Feel More Tired
The mental enrichment your dog gets on a slow walk with lots of time for sniffing is much greater than they would get on a fast-paced, walk to heel. This means a shorter sniffy walk can tire them out and they will generally be more relaxed and less likely to exhibit destructive or mischievous behavior when at home.back to menu ↑
