Why Do I Smell Like A Wet Dog After Being Outside?

Have you ever wondered why you sometimes end up smelling like a wet dog after spending time outdoors? The peculiar odor can be embarrassing and frustrating. In this article, we will delve into the science behind the “wet dog” smell, exploring its causes and offering effective strategies to prevent and combat the odor. By understanding the underlying mechanisms and implementing proper hygiene practices, you can confidently enjoy outdoor activities without the fear of smelling unpleasant.

The Biology of the “Wet Dog” Smell

Understanding the OdorBacterial and Fungal Growth: The primary culprits behind the wet dog smell are bacteria and fungi that naturally reside on the skin and fur. When you get wet, moisture becomes trapped in your clothes and hair, creating a warm and humid environment ideal for microbial growth. These microorganisms break down organic compounds on your skin, such as sweat and sebum, releasing volatile organic compounds (VOCs) responsible for the distinctive odor.

8 Factors Influencing Odor Intensity:

  1. Outdoor Environment: Spending time outdoors can intensify the wet dog smell due to increased exposure to dirt, allergens, and pollen. These particles can stick to your clothes and hair, amplifying the odor.
  2. Individual Factors: Certain personal factors, such as metabolism, diet, and overall health, can influence the production and strength of body odors. Some individuals may naturally produce more VOCs, contributing to a stronger wet dog smell.
  3. Breed and coat type: Certain dog breeds, such as those with double coats or thick fur, are more prone to retaining moisture, making them more susceptible to the wet dog smell. Breeds like Retrievers, Spaniels, and Poodles are examples of dogs with hair types that can retain moisture easily.
  4. Inadequate drying: If a dog is not dried thoroughly after getting wet, moisture can remain trapped in their fur, providing an ideal environment for bacteria and fungi to grow and thrive.
  5. Poor hygiene: Lack of regular grooming, including brushing and bathing, can contribute to the accumulation of dirt, dead skin cells, and oils on a dog’s coat, leading to an increased likelihood of the wet dog smell.
  6. Skin issues: Dogs with certain skin conditions, such as seborrhea or yeast infections, may be more prone to emitting a stronger wet dog odor due to imbalances in the skin’s microbiome.
  7. Diet: A dog’s diet can affect their skin and coat health. Poor nutrition or certain food ingredients may lead to an imbalance in the skin’s natural oils, making it more prone to odor-causing bacteria and fungi.
  8. Medical conditions: In some cases, underlying medical conditions such as skin infections, allergies, or hormonal imbalances can contribute to an intensified wet dog smell.

By understanding the causes and contributing factors of the wet dog smell, you can take appropriate measures to prevent and minimize the odor.

4 Strategies to Prevent and Combat the Wet Dog Smell

Proper Hygiene Practices:

a) Regular Bathing: Frequent bathing helps remove bacteria and fungi from your skin and hair, reducing the likelihood of the wet dog smell. Use mild, pH-balanced cleansers and thoroughly dry yourself after bathing.

b) Clothes and Gear: Wash your clothes regularly, particularly after outdoor activities, using laundry detergents that effectively eliminate odors. Properly clean and maintain your gear, including shoes, jackets, and sports equipment.

Managing Sweat and Moisture:

a) Quick Drying: Change out of wet clothes as soon as possible to prevent prolonged moisture exposure. Towel dry yourself thoroughly after getting wet, paying attention to skin folds and creases.

b) Breathable Fabrics: Opt for clothing made of breathable materials that allow air circulation, reducing the likelihood of trapped moisture and odor buildup.

c) Underarm Hygiene: Keep your underarms clean and dry, as the region has a high concentration of sweat glands. Use antiperspirants or deodorants to control perspiration and odor.

Personal Grooming and Care:

a) Hair Care: Properly clean and dry your hair, paying attention to the scalp. Regularly wash and condition your hair using products designed to combat odor and maintain scalp health.

b) Oral Hygiene: Brush your teeth at least twice a day and use mouthwash to keep your breath fresh and prevent any potential contribution to body odor.

c) Skin Care: Use gentle cleansers and moisturizers suitable for your skin type. Exfoliate regularly to remove dead skin cells, promoting a healthier skin barrier.

Diet and Lifestyle Considerations:

a) Hydration: Stay adequately hydrated to help regulate body temperature and minimize excessive sweating.

b) Balanced Diet: Consume a well-balanced diet rich in fruits, vegetables, and lean proteins. Avoid foods with strong odors, such as garlic and onions, which can contribute to body odor.

c) Alcohol and Tobacco: Limit or avoid excessive alcohol consumption and tobacco use, as they can contribute to body odor.

Can the wet dog smell be caused by a medical condition?

Yes, in some cases, a persistent or strong wet dog smell can be caused by an underlying medical condition. Skin infections, yeast overgrowth, seborrheic dermatitis, or other skin disorders can contribute to an intensified odor. If you notice that your dog’s odor persists despite proper hygiene practices, it is recommended to consult with a veterinarian for a thorough examination and appropriate treatment.

How can I eliminate the wet dog smell from my clothing?

To eliminate the wet dog smell from clothing, you can try the following methods:

  • Pre-soaking: Soak the affected clothing in a mixture of water and white vinegar for about 30 minutes before washing.
  • Odor-neutralizing products: Use laundry detergents or additives specifically formulated to eliminate stubborn odors. These products can help break down and remove the odor-causing compounds.
  • Sun-drying: After washing, hang the clothing outside in direct sunlight, as the sun’s UV rays can help naturally eliminate odors.

Are there any specific dog breeds that cause this odor in humans?

While all dogs have the potential to develop the wet dog smell, certain breeds may be more prone to it. Breeds with thick double coats or curly hair types, such as Retrievers, Spaniels, and Poodles, are more likely to retain moisture in their fur, increasing the chances of emitting the wet dog odor. However, it is important to note that individual variation, grooming practices, and overall hygiene also play a significant role.

Can certain foods or medications contribute to the wet dog smell?

Yes, certain foods and medications can potentially contribute to an intensified wet dog smell. Foods with strong odors, such as fish-based diets, can affect the scent of a dog’s coat and skin. Additionally, certain medications or supplements may alter the natural oils on a dog’s skin, potentially leading to an increased likelihood of odors. If you suspect that your dog’s diet or medications may be contributing to the wet dog smell, consult with your veterinarian for appropriate recommendations.

Is it possible to prevent the wet dog smell completely?

While it may be challenging to completely prevent the wet dog smell, implementing proper hygiene practices, regular grooming, and maintaining a clean environment can significantly reduce the intensity and frequency of the odor. By following the tips mentioned in this article, you can minimize the wet dog smell and keep your dog smelling fresh. However, individual factors such as breed, coat type, and overall health can influence the odor, so complete prevention may not be feasible for all dogs.


The wet dog smell after being outdoors can be unpleasant, but with the right knowledge and practices, you can effectively prevent and combat it. By understanding the biology behind the odor, implementing proper hygiene practices, managing sweat and moisture, and considering diet and lifestyle factors, you can significantly reduce the intensity and frequency of the wet dog smell. Remember, maintaining good personal hygiene and following the strategies outlined in this article will help you confidently enjoy your outdoor adventures without worrying about the lingering odor.
