My Dog's Feet Smells Like Fritos!

I wasn't aware that dogs could even get a yeast infection on their feet. I mean, I suppose any area that is damp could get it, but my dog's feet are typically pretty dry if anything. Do you know how this happens? Are the yeast feeding off of the dog's sweat or skin or something?

Also, since the yeast got me thinking - is it possible for a dog to get a fungal infection on its feet? Something like athletes food that humans can get? Would any of these be transmissible to humans or are they specific to canines? To my knowledge, my dog has never had an issue with a yeast infection (as she doesn't smell like Fritos hehe), and she's in the water quite often being a lab. She got an ear infection once, but that's about it.
