Why Do Dogs Lick Stinky Feet? Unraveling the Mystery
Dogs lick stinky feet for a variety of reasons, ranging from curiosity about unique scents to displaying affection, seeking attention, or even trying to clean. Understanding the underlying motivations can help owners manage this behavior.
The Nose Knows: The World of Dog Olfaction
Dogs possess an incredible sense of smell, far surpassing that of humans. Their olfactory system is significantly more developed, allowing them to detect minute scent variations and differentiate between a vast array of odors. Why do dogs lick stinky feet from an olfactory perspective? Essentially, the “stinky” aspect is what grabs their attention. Feet, especially those that have been confined in shoes, accumulate a complex mixture of sweat, bacteria, and shed skin cells, creating a unique odor profile that a dog’s nose finds intensely interesting.
- Enhanced Olfactory Receptors: Dogs have approximately 300 million olfactory receptors in their noses, compared to about 6 million in humans.
- Dedicated Olfactory Brain Region: The part of a dog’s brain dedicated to analyzing smells is about 40 times larger than the corresponding area in humans.
- Jacobson’s Organ (Vomeronasal Organ): This specialized sensory organ detects pheromones, chemical signals that play a crucial role in communication and social behavior.
The Taste Connection: Why Licking Follows Sniffing
Once a dog is intrigued by a scent, licking often follows. Licking allows the dog to further investigate the source of the odor, gathering additional information about its composition. Why do dogs lick stinky feet rather than just sniffing? The act of licking can also release pleasurable endorphins in the dog’s brain, reinforcing the behavior.
- Sensory Exploration: Licking provides another layer of sensory input, allowing the dog to analyze the taste and texture of the substance.
- Endorphin Release: The act of licking can be self-soothing and pleasurable for the dog.
- Hygiene(?): Although unlikely to be the primary motivation, a dog might instinctually attempt to clean or groom by licking.
Behavioral and Emotional Factors
Beyond the scientific explanation, behavioral and emotional factors also contribute to why dogs lick stinky feet.
- Affection: Licking can be a sign of affection, similar to grooming. The dog may be trying to bond with its owner.
- Attention-Seeking: If the dog has learned that licking feet results in attention (even negative attention), it may repeat the behavior to get a reaction.
- Anxiety or Boredom: Excessive licking can sometimes be a sign of anxiety or boredom.
Addressing the Behavior: Strategies for Owners
While licking itself is generally harmless, excessive or obsessive licking can be problematic. Here are some strategies to manage this behavior:
- Rule out Medical Causes: Consult with a veterinarian to rule out any underlying medical conditions, such as skin allergies or nutritional deficiencies.
- Provide Alternative Enrichment: Offer plenty of toys, exercise, and mental stimulation to alleviate boredom and anxiety.
- Ignore the Behavior: If the dog is licking for attention, try ignoring the behavior to avoid reinforcing it.
- Redirect the Behavior: When the dog starts licking, redirect its attention to a toy or command.
- Consult a Professional Trainer: If the behavior is persistent or problematic, seek guidance from a certified dog trainer or behaviorist.
Foot Hygiene: A Simple Solution
A practical step is also to improve foot hygiene. Regular washing of feet can greatly reduce the interesting (to the dog) scents and bacteria. This isn’t to eliminate all human odor, but to minimize the overwhelming attractant.

Frequently Asked Questions About Dogs Licking Stinky Feet
What exactly makes feet so smelly to dogs?
The distinctive odor of “stinky” feet is a complex cocktail of sweat, bacteria, and shed skin cells. The bacteria break down the sweat, producing volatile organic compounds that create the unpleasant smell. Different types of bacteria produce different odors, contributing to the unique scent profile that fascinates dogs.
Is it harmful for my dog to lick my feet?
Generally, it’s not directly harmful, but it’s not recommended. Human feet can harbor bacteria and fungi that could potentially cause mild gastrointestinal upset in dogs. Additionally, open wounds or cuts on the feet could expose the dog to infection.
My dog only licks my feet after I’ve been to the gym. Why is that?
Increased physical activity leads to more sweating, creating a stronger and more appealing odor profile for your dog. The combination of sweat and the specific bacteria that thrive in a gym environment makes your feet particularly interesting after a workout.
How do I stop my dog from licking my feet at night?
Consistency is key. Gently remove your feet when your dog starts licking, and avoid giving any attention (positive or negative). You can also provide a chew toy or blanket for your dog to focus on instead. If the licking seems related to anxiety, consult with your vet about possible solutions.
Could my dog be licking my feet because of a nutritional deficiency?
While less common, nutritional deficiencies can sometimes lead to unusual cravings and behaviors, including licking. It’s always a good idea to discuss your dog’s diet with your veterinarian to ensure they are getting all the necessary nutrients.
Is licking feet a sign of dominance in dogs?
While licking can sometimes be a part of the social hierarchy in dog packs, it’s rarely about dominance when licking humans’ feet. In most cases, it’s more related to affection, attention-seeking, or the allure of the scent.
My dog only licks one person’s feet in the household. Why?
This likely means that the dog finds the scent of that person’s feet particularly appealing. It could be due to differences in sweat composition, bacteria, or even the type of footwear they wear. The dog may also have a stronger bond with that individual.
Could my dog be licking my feet to clean them?
While dogs do engage in grooming behavior, it’s unlikely that they are licking your feet primarily to clean them. The main driver is usually the scent and taste.
My dog is obsessed with licking feet, even when they aren’t “stinky.” What should I do?
If your dog is obsessively licking feet, it’s important to rule out any underlying medical or behavioral issues. Consult with your veterinarian and a professional dog trainer or behaviorist to develop a tailored management plan.
Does the type of shoe I wear affect how much my dog licks my feet?
Yes, the type of shoe can significantly impact the odor and thus the dog’s interest. Shoes made of synthetic materials tend to trap more moisture and heat, creating a breeding ground for bacteria and increasing the “stinkiness” of the feet.
Is it possible to train a dog to stop licking feet completely?
Yes, with patience and consistency, it is possible to train a dog to stop licking feet. Using positive reinforcement techniques, such as rewarding alternative behaviors (e.g., sitting, staying), can be very effective. Professional guidance is often beneficial.
Why do dogs lick stinky feet, but seem repulsed by other strong smells?
The key is the complexity and familiarity of the scent. While dogs have a powerful sense of smell, they are not attracted to all strong smells. The mix of human sweat, bacteria and skin, creates a unique blend that dogs find highly interesting and may even contain pheromones or chemicals related to the person the dog is bonded with. Offensive smells, from a human perspective, might also overwhelm or be unfamiliar and trigger an avoidance response. Why do dogs lick stinky feet is still a matter of personal taste, even in the canine world.
