The Short Answer

"Frito feet" is caused by Pseudomonas and Proteus bacteria that naturally live on your dog's paws. These bacteria produce organic compounds that smell exactly like corn chips or Fritos. It's completely normal and harmless. If the smell is very strong or accompanied by redness, licking, or swelling, it could indicate a yeast infection.
