Why are scents and smells so important?
Odours or scents can be perceived with the help of the nose via so-called chemoreceptors, which interpret sensory stimuli and transmit the signals to the brain. Every living creature on earth has a different number of chemoreceptors, sometimes more and sometimes less. For us humans, smell is used primarily to be able to taste, but also to be stimulated by pleasant odours and to be linked to feelings and emotions. Without odours and their perception, the quality of life would be significantly reduced. On the other hand, animals need the perception of odours and scents first of all to identify conspecifics, family members, enemies and their territories better. Furthermore, odours also serve to identify what is food and what is rotten, which are separated from each other by different odour substances.
Why does my dog have a bad smell?
Dogs as any other living creature also have their own natural smell. This is also differently dependent on the breed and can be different strong or weak. However, there are many different reasons why dogs can "have a bad smell".
Rolling in dirt and mud

A big aspect why dogs can have a stronger smell is that they love it to roll around in dirt and mud. They do not like pleasant scents like we humans e.g. perfumes and shampoos with fragrances but rather the "natural" scent. This also has its sense and purpose, because dogs are derived from the wolves. Through years of evolution the instinct of not being discovered by enemies is still present. So this was an advantage over the enemy, not to get caught, but to deceive him, so that it would not be perceived as " eatable". In addition, wolves rolled over in order not to be detected by their prey and to hunt them away. Rolling in dirt and filth was thus a tactical and necessary activity of the wolf, which was transferred to the house dog. A dog bath can remove the dirt and neutralize smells. It should also be noted that only dog shampoos without odorous substances are to be used.

Wet fur

When the dog's fur starts to smell more intensive, it can be caused by the fact that the fur has come into contact with wetness. This is usually a rather common but harmless cause. The reason for this is that the scents that dogs produce are water-soluble. This makes it much easier for these substances to be spread, causing an increased and unpleasant scent . There may also be other reasons for the bad smell, such as:


  • sweat

  • germs

  • fungal infestation

  • infections

  • Skin irritation


For the last four reasons listed above, a veterinary consultation is urgently recommended.

Health causes

If dogs have a more unpleasant smell than usual, there may also be medical causes. However, this is rarely the case, but cannot be excluded. Therefore, if a dog has an unpleasant smell, a self-diagnosis can always be useful. However, if a serious condition is suspected, a visit to the veterinarian should not be avoided.


Possible causes of bad smells can be


  • if the dog has bad breath

  • when the ears stink

  • if the dog stinks because of wrong food

  • if the dog smells unpleasant due to age

If the dog has bad breath

If unpleasant odours are noticeable after eating, this is not entirely unusual. If there is no health reason for it, the typical smell after the meal can disappear by itself after some time. If the bad breath doesn't disappear even after a longer period of time, the teeth should be examined closer. This often indicates gum infections, which can be caused by poor mouth hygiene. This can be an indication that the smell from the mouth should be taken seriously because of redness, swelling, tartar or even bleeding gums. As a rule, it can be cured by taking good oral hygiene measures. For example, dry food instead of canned food can ensure that dogs "chew away" tartar build-up when they eat. Chewing articles such as chewing bones, chewing roots or antlers can also help to improve oral hygiene. In addition, the teeth can be cleaned with a toothpaste and toothbrush specially developed for dogs. This can help to significantly reduce bacteria on the teeth and gums, thus ensuring optimal oral hygiene for the dog. However, the procedure is only possible if dogs allow it, which is not always the case. Additives that can be added to the food or water can also help to improve the oral flora. If these initial measures do not help, a visit to the veterinarian should take place. The reason for this is that bad breath can rarely be caused by internal organs such as the stomach or throat.

When the ears stink

If the ears smell, they should be observed. After all, of the five sensory organs, they are among the most important of a dog. Dogs can register sounds even from a distance of 500m and perceive frequency ranges of up to 50.000Hz (i.e. 50.000 vibrations per second), which people with good ears can only hear up to 20.000Hz.

Unpleasant odours from dogs' ears can be a sign of infection. In the case of an infection, "only" the outer ear is usually affected, i.e. from the auditory canal to the eardrum and the pinna. Dogs also show this by often shaking their head and rubbing their ears against objects.

Middle ear infections can also appear, but rarely. These are then associated with severe symptoms such as loss of balance and tilting of the head. Possible causes of an ear infection can be allergies, diseases, ear mites, foreign particles or too much faulty ear cleaning. The shape and type of the ears also plays a role. Due to the right climate, floppy ears with hair in the ear canal may have a higher risk of infection and germs than dogs with pointed ears.

In order to get rid of the odours and thus the infections a visit to the veterinarian is necessary. He can then diagnose exactly what kind of infection it is and what measures need to be taken. In very mild cases ear cleaners can be used. These contain active ingredients that kill germs, remove dirt and support the healing process.

If the dog stinks because of wrong food

Food plays a major role in the elimination of unpleasant odours from the coat and skin. This is because high-quality food that is rich in substances can cause fewer degradation products in dogs' bodies, so they smell less unpleasant. With so-called chlorophyll tablets, dog odour can be reduced without harming the four-legged friends, as they are based on natural substances. High-quality dog food can be used by the body optimally and completely and thus reduce dog odours. In addition, it can be used to reduce the odour of the dog.
Poor quality dog food, can cause the food to be not fully consumed and residues can cause unpleasant odours through the coat.

Another reason why dogs can generally smell more intensely is that they are given too many snacks. This is because they strongly stimulate the gastrointestinal tract, which is the result of an unpleasant dog smell forming over the coat.

If the dog smells unpleasant due to age

Like us humans, our four-legged friends are not saved from ageing at some point. This is the natural cycle of life. With increasing age dogs start to smell much stronger. This process is completely normal. The reason for this can be the increased sebum production in the coat. In order to prevent this, only regular grooming can help, which means that the smelly parts can be combed out of the coat. A grooming with a coat brush can have a wonderful effect. Also bathing dogs in older dog years can help to counteract the unpleasant smell. It should be noted that milder care products and no perfume additives should be used to avoid irritating the sensitive skin.
