It's not like we're tryna smell their feet. If you have a dog and you're not a heartless monster, have covid nose, or some other smelling disorder, you're gonna smell your dogs feet whether you try to or not.
You know how a person farts and then crop dusts you by walking past? Dogs kinda do that with Frito feet. They walk past you or sit near you and then all of a sudden you smell Fritos. It's for sure a thing. You don't need to smell their feet to pick up the scent.
When you're first exposed to Frito feet for the first time, you end up smelling around until you find the source, but after that no need to get close and sniff. It's not unpleasant, just kinda weird because your brain is legit looking for the open bag of Fritos.
It really depends on the dog. I've known some who don't and some who do. Essentially it's all dependent on hygiene, pheremones, bacteria, and fungi they pick up. My last dog was very into keeping her paws clean. She didn't get muddy and liked when we wiped her paws down if she was in the rain, so hers didn't smell at all.
if your dog smells like corn chips, especially in paw, it means there is a build up of yeast bacteria. Could be caused by them being dirty, eating too much processed food, or if your dog licks their paws a lot.
Feed your dogs better food and bathe them more regularly if they frequently smell like corn chips.
