My Dog's Feet Smells Like Fritos!

I am having the same problem with my puppy her paws are starting to have that frito smell, at first when I smelled it I began to clean the house because I thought it was something in my house, and then I began yelling at my boyfriend about his feet because I thought it was him. But then I was playing with my pup and sure enough it was her so I began to give her baths every week but the smell comes back after a few days. I guess that is just a part of her charm...frito feet.
