Question: ‘Frito Feet’ – Why Do Dog Paws Smell Like Corn Chips, Nuts, or Popcorn?

Questions about pet odors are common. Often a bad smell indicates a problem or disease process, but not always. What should you do if you notice that your dog’s feet have a odor, often described as smelling like corn chips or old popcorn? Is this something to worry about? Read this FAQ to find out more about what is commonly termed “Frito Feet.”


Bacteria and fungi live on the skin of healthy animals, including dogs and cats. The feet, being what they are – on the ground, walking in stuff, and occasionally licked by the dog’s tongue (containing additional microbes) – may have more of an odor than the rest of the body. And thankfully, this faintly-food-related smell is, in most cases, just a curiosity.

But what if this odor is a problem?


There are many possible conditions that could cause a foul odor of feet. Here are a few:

  • Bacterial or fungal infection (overgrowth of normal or pathologic microbes causing disease)
  • Grass awn or other foreign body causing an irritation or abscess.
  • Skin tumor (e.g. foot melanoma) or lick sore that has become ulcerated or infected.
  • Toe nail injury or nail bed infection.
