Why do dogs stink? In this article, you will learn about the reasons behind the unpleasant odor that dogs sometimes have. We will explore the various factors that contribute to this issue, including breed, diet, and overall health. By understanding the underlying causes, you will be better equipped to address and manage your dog’s odor, ensuring a more pleasant living environment for both you and your canine companion.
Dogs are wonderful companions, but one thing that can be quite unpleasant is their odor. If you’ve ever found yourself wondering why your furry friend smells so bad, read on to discover the causes of dog odor and how you can prevent it.

Causes of Dog Odor

Poor hygiene

Just like humans, dogs need regular bathing and grooming to maintain good hygiene. If your dog isn’t receiving proper grooming, dirt and bacteria can build up on their skin, resulting in a foul odor. It’s important to brush your dog’s coat regularly to remove any dead hair and debris. Additionally, make sure to clean their ears and trim their nails as part of their grooming routine.

Skin infections

Skin infections are a common cause of dog odor. Dogs can develop bacterial or fungal infections on their skin, leading to unpleasant smells. These infections can be triggered by a variety of factors, including allergies, parasites, or even just excessive moisture on the skin. If you notice redness, itching, or a strong odor coming from your dog’s skin, it’s crucial to consult a veterinarian for proper diagnosis and treatment.

Anal gland issues

Dogs have two anal glands on either side of their anus, which produce a strong-smelling fluid. Normally, these glands empty naturally when a dog defecates. However, sometimes these glands can become impacted or infected, leading to a pungent odor. If you notice your dog dragging their bottom or excessively licking their rear end, it could be a sign of anal gland problems. A trip to the vet is necessary to alleviate this discomfort and prevent further issues.

Diet and Dog Odor

Low-quality dog food

What your dog eats plays a significant role in their overall health and odor. Low-quality dog food can contain fillers and artificial ingredients that are difficult for dogs to digest. This can result in gastrointestinal issues and smelly stools, which in turn can contribute to an unpleasant odor. Opting for high-quality dog food that is rich in nutrients and free from artificial additives can help improve your dog’s digestion and reduce odor.

Food allergies

Food allergies can also lead to dog odor. Just like humans, some dogs are sensitive to certain ingredients in their food. Common allergens in dog food include grains, beef, chicken, and dairy products. If your dog has food allergies, they may experience symptoms such as excessive scratching, hair loss, and a distinctive odor. Consult with your vet to determine the underlying allergen and switch to a hypoallergenic diet if necessary.

Breeds Prone to Odor

While all dogs have the potential to develop a distinct smell, some breeds are naturally more prone to odor than others. Here are a few breeds that are known for their unique aromas:

Basset Hound

Basset Hounds have long, droopy ears and deep facial folds, which can trap moisture, dirt, and bacteria. This can lead to odor if not properly cleaned and dried.


Bloodhounds have a strong, musky scent that comes from their skin. Regular bathing and grooming are essential to keep this odor under control.

Shar Pei

The Shar Pei breed is known for its wrinkled skin. While these wrinkles are adorable, they can also trap dirt and moisture, creating an unpleasant smell. Regular cleaning and drying of the wrinkles can help prevent odor.

Environmental Factors

Excessive humidity

Humidity can worsen dog odor, as it promotes the growth of bacteria and mold. If your living environment is consistently humid, it can contribute to a persistent smell in your dog. Consider using dehumidifiers or ensuring proper ventilation in your home to reduce moisture levels.

Mold in the living area

Mold can also be a culprit behind dog odor. If you suspect mold growth in your living area, it’s important to address this issue as it can affect both human and pet health. Clean any visible mold and consider consulting a professional for proper removal if the problem persists.

Behavioral Causes of Odor

Rolling in foul-smelling substances

Dogs have a unique habit of rolling in foul-smelling substances, such as dead animals or feces. While this behavior may be instinctual or may serve a purpose in the wild, it can result in a rather pungent odor. If your dog enjoys this activity a bit too much, it’s best to keep them on a leash during walks and closely monitor them in outdoor areas.

Lack of grooming

As mentioned earlier, regular grooming is essential for maintaining good hygiene in dogs. If you neglect to groom your dog, their coat can become dirty, matted, and smelly. It’s important to establish a grooming routine, including regular brushing, bathing, and nail trimming, to keep your dog smelling fresh.

Health Conditions

Ear infections

Ear infections can cause a distinct odor in dogs. The warm and moist environment inside their ears provides an ideal breeding ground for bacteria and yeast. Dogs with long, floppy ears are particularly susceptible to ear infections. If you notice your dog shaking their head, scratching their ears, or emitting a strong odor from their ears, it’s crucial to seek veterinary care for proper diagnosis and treatment.

Oral problems

Dental hygiene plays a significant role in overall odor. Dogs can develop dental issues such as gum disease, tooth decay, and tartar buildup, which can lead to bad breath and a foul smell. Regular brushing of your dog’s teeth, along with veterinary dental cleanings, can help keep their oral health in check and prevent odor.

Urinary tract infections

Urinary tract infections can cause a distinctive odor in your dog’s urine. If you notice a strong, unpleasant smell coming from your dog’s urine or if they are exhibiting signs of discomfort while urinating, it’s important to consult a veterinarian. Prompt treatment is necessary to prevent further complications and discomfort for your furry friend.

Preventing Dog Odor

Regular grooming

Regular grooming is key to preventing dog odor. Brushing your dog’s coat helps remove dirt, debris, and dead hair that can contribute to odor. Additionally, bathing your dog with a gentle, dog-friendly shampoo can keep their skin clean and fresh-smelling. Don’t forget to trim their nails, clean their ears, and brush their teeth as part of their grooming routine.

Proper dental care

As mentioned earlier, dental hygiene is crucial in preventing dog odor. Establish a dental care routine that includes regular brushing of your dog’s teeth with a dog-specific toothbrush and toothpaste. This helps remove plaque and tartar buildup, which can lead to bad breath and a foul smell.

Clean living environment

Maintaining a clean living environment is essential to preventing dog odor. Regularly clean your dog’s bedding, blankets, and toys to remove any trapped odors. Vacuum and mop your floors to reduce pet dander and minimize allergens. Ensure good ventilation to prevent excessive humidity, which can worsen odor.

Why Do Dogs Stink

Natural Remedies

Apple cider vinegar baths

Apple cider vinegar has natural antibacterial properties and can help eliminate odor-causing bacteria from your dog’s skin and coat. Dilute apple cider vinegar with water and use it as a rinse after bathing your dog. This can help neutralize odors and promote a healthy skin pH.

Probiotics for gut health

Probiotics can help improve your dog’s overall gut health, which can in turn reduce odor. Probiotic supplements or adding probiotic-rich foods, such as plain yogurt, to your dog’s diet can help balance their digestive system and minimize odor.

When to Seek Veterinary Help

Persistent strong odor

If your dog has a persistent strong odor that doesn’t improve with regular grooming and hygiene practices, it’s important to consult a veterinarian. Persistent odor can be a sign of an underlying health issue that requires medical attention.

Unusual changes in odor

If you notice any unusual changes in your dog’s odor, such as a sudden increase in intensity or a particularly foul smell, it’s best to seek veterinary advice. Unusual changes in odor can be indicative of an infection or other medical condition that needs to be addressed promptly.


While dogs may have a natural scent, several factors can contribute to unpleasant odors. Poor hygiene, skin infections, anal gland issues, diet, environmental factors, behavioral causes, and health conditions can all play a role in dog odor.
By understanding the causes and taking preventive measures such as regular grooming, proper dental care, and maintaining a clean living environment, you can help keep your canine companion smelling fresh and healthy. Remember, if you notice persistent or unusual changes in your dog’s odor, it’s always best to consult a veterinarian for proper diagnosis and treatment.
