Even in the grocery store, where I know I will not find dog food I'm willing to give Elka, I still go down the dog aisle. I look at the treats, and the ingredients of food, squeeze squeaky toys and look for tennis balls that I have not bought before. I'm sure I must have an interesting look on my face, depending on the object of my attention; horror or disgust when it comes to the food ingredients, amusement when it comes to the durability of the toys (or lack thereof). I do buy things, once in awhile.
I do occasionally buy the Rachael Ray Just 6 treats, because they do, in fact, have only six ingredients (which could be worse), and Elka seems to like them well enough. There's apparently a "Just 6" kibble now as well; it has many many 6's of ingredients. I will not buy it.
Recently, I bought a bag of chicken flavored "Soup bones" for Elka. It's doggie junk food, I'm not fooling myself, but every once in awhile, I look for something to give her that I think might occupy her for a little while, or interest her.
