Introduction: The Curious Case of the “Frito Feet” Smell
How your dog smells can say a lot about their health. Sometimes, dogs develop a corn chip-like smell around their ears or between their paws. This smell is like pungent cheese and can be described as the smell of tortilla chips or Fritos. Pet parents typically notice this smell while grooming their dogs or when petting them.
If you are also asking yourself “Why does my dog smell like Fritos?” this guide will help you. One of the main causes of a pungent cheese-like odor in dogs' paws is the bacteria and fungi on their skin and paws. An overgrowth of these bacteria or yeast leads to this cheesy smell. Sometimes, a dog with anal gland issues could also emit a foul, stale, cheese-like odor.
If the smell is more pronounced around the dog’s ears, an ear infection could be the cause. Dental diseases can also result in such weird smells in dogs. In some cases, dogs that are fed highly processed food could also develop abnormal odors reminiscent of cheese or Frito chips.
What Causes the “Fritos” Smell in Dogs?
Natural Bacteria on Your Dog’s Skin and Paws
If you have been thinking, “My dog smells like Fritos,” then the natural bacteria on their paws could be the culprit. Bacteria such as Proteus and Pseudomonas are naturally present in a dog’s paws. These microbes interact with the dog’s sweat and saliva, resulting in a sour, Fritos-like smell. Worry not: these bacteria are a natural part of your dog’s microbiome, but their overgrowth sometimes causes that yeasty smell on dogs’ paws.
Sweat Glands and Paw Anatomy
According to the experts at the AKC, dogs’ paws and toes are structured in a manner that creates a natural breeding ground for bacteria and fungi. This region contains your dog’s sweat glands, and sweating through the paws is one of the mechanisms that helps dogs regulate their body temperature. However, this gap between their toes and paws traps moisture and dirt, creating a perfect environment for microbes to thrive. This results in a pungent, cheesy odor.
Poor Diet
Dogs that are fed heavily processed food could sometimes develop a foul body odor. If a dog’s diet is rich in additives, sugar, preservatives, and other unwanted ingredients or byproducts, they could develop a cheesy odor around their ears, paws, etc., due to an overgrowth of candida or yeast.
Other Underlying Health Issues: Dental Problems and Anal Gland Disease
Sometimes, dogs with underlying health issues or oral diseases could also develop a malodor. Periodontal disease or broken teeth in dogs could cause halitosis and bad breath. Similarly, an anal gland infection could result in infected anal sacs with fluid buildup that smells like rotting cheese.
Is the Frito Smell Normal or a Sign of a Problem?
When It’s Harmless
Sometimes, the question “Why do dogs paws smell like Fritos?” has a simple, reassuring answer: it’s perfectly normal. Healthy, active dogs are bound to have the Fritos-like smell on their dog feet.
This cheese-like or tortilla-like smell is completely normal if they are otherwise active and healthy. However, they should not be constantly licking their paws or scratching their ears. Moreover, there should be no irritation, redness, oozing blisters, rashes, hair loss, etc., around their paws.
When It Might Be a Health Concern
If the Fritos smell is very strong or your dog is constantly licking their paws, then it could be something more serious. If the area on the paws appears red, crusty, and irritated, then your dog could have a yeast infection or some skin problem.
Sometimes, dogs with yeast overgrowth could also have infected ears, wrinkled skin, tear stains, patchy hair loss, irritated red skin, blisters, or oozing rashes. If this describes your dog, then it may be time to take them to the vet.
Condition | Normal | Needs Vet Attention |
Appetite | Regular interest in food | Sudden loss or excessive increase in appetite |
Eating Speed | Moderate, consistent pace | Eating too fast or refusing food |
Weight Change | Stable over time | Sudden weight loss or gain |
Water Consumption | Regular drinking | Excessive thirst or no water intake |
Tip: Always monitor changes over a few days before jumping to conclusions.
Common Triggers That Make the Smell Worse
Moisture and Warm Environments
Some dog owners notice that their dog’s cheesy odor is more pronounced in rainy or damp weather. If your dog walks in the rain, loves splashing in puddles, and tracks the dirt home, then it is likely that you are washing their paws. Despite your best intentions, you might leave their paws moist. The humidity in the air further prevents their paws from drying quickly. This results in a more pronounced Fritos-like odor.
Dirty Bedding and Surfaces
If your dog sleeps or walks on dirty floors, carpets, rugs, bedding, or an unwashed crate, chances are that their paws pick up the dirt and microbes from these surfaces. This, too, can result in a strong tortilla-like or cheese-like odor over time.
Allergies and Excessive Licking
The most common reason behind the strong cheesy odor in dogs’ paws is allergies. Food and other environmental allergies tend to inflame your dog’s paw tissues. A dog with allergies is more likely to lick their paws until they are raw and inflamed. Such dogs often also have ear infections with discharge.
It becomes a vicious cycle, as your dog tries to soothe their irritated paw by licking, but their saliva further interacts with the bacteria, resulting in an overgrowth of microbes. This worsens the infection and the Frito-like smell.
How to Get Rid of the Frito Smell
Clean Your Dog’s Paws Regularly
If you have been thinking, “My dog smells like Fritos,” then unhealthy dog paws could be the reason. Start cleaning their paws with mild, unscented pet wipes or soap-free paw-cleaning solutions or sprays.
Wash and dry your dog’s paws thoroughly after they walk in the rain or play in the dirt. Take care not to leave their paws wet after a bath. You want to avoid moisture, which is the main reason behind yeast or Candida overgrowth in the dog’s paw region.
Bathe and Groom Your Dog Appropriately
In the case of long-haired or furry dogs, trimming the hairy paws can prevent the overgrowth of microbes, fungi, and bacteria.
If your dog suffers from recurrent bacterial or fungal skin issues, use a vet-approved antibacterial or antifungal shampoo to wash and clean their paws.
Wash Bedding and Toys Frequently
Even if you bathe and groom your dog, the fungal spores can remain dormant on their bedding and other surfaces such as dirty rugs, carpets, and crate floors. So, regularly clean these areas to limit yeast infections in dogs.
Where possible, toss their bedding in the washing machine to thoroughly clean it. If it is not possible to clean these items at home, get them professionally dry-cleaned. Always use pet-safe detergents or soaps to clean your pet’s blankets, beds, and toys.
Vacuum and wash all rugs and carpets using pet-friendly cleaners, shampoos, or wipes. A solution of vinegar and baking soda sprayed on these surfaces can also do the job.
When to See the Vet
Signs That It’s More Than Just a Smell
As can be seen, the Fritos smell on your dog is normal, to some extent. However, if your dog has red, irritated paws or they are constantly licking them, then it could be something more serious. Watch out for signs of unhealthy dog paws, such as limping, excessive scratching or licking, brownish discharge from blisters, rashes, sores, or crusting in the paw region. If you notice these signs, please see your vet.
Potential Diagnoses
Yeast infection or dermatitis
As per the experts at VCA, yeast dermatitis, or Malassezia dermatitis, is one of the common yeast infections in dogs. Malassezia yeast is naturally present on the dog’s body, particularly in the paw area. However, an abnormal overgrowth of this yeast can result in odor, itching, redness, crusty/flaky paws, thickened skin, and chronic ear infections.
Pododermatitis
Several factors can result in pododermatitis or inflammation of a dog’s paws. In addition to bacteria, yeast, and fungal infections, seasonal or food allergies, hormonal issues, contact dermatitis from walking or running on hard surfaces, trauma, etc., can all cause canine pododermatitis.
Final Thoughts: Love It or Leave It (With a Vet Visit)
You may still be wondering, “Why does my dog smell like Fritos?” We do hope this guide has helped you. Frito smell on your dog's feet is usually normal as long as it is mild. However, do not ignore the red flags like crusting, oozing, or constant licking or scratching accompanied by ear infections, limping, and other signs of discomfort.
Always monitor your dog’s paws during bathing or grooming. Clean their paws regularly. Regular vet checks and grooming should keep your pet’s paws fresh and healthy.
