These days, a trip down the dog food aisle of your local pet store or supermarket can be a little overwhelming. There are hundreds of brands out there, catering to – let's be honest – every dog owner's taste: everything from generic kibble to organic nuggets.
There are even dog food cookbooks and specialty gourmet shops for people who want their pets to eat as well – or better – than they do.
How did we get here? The first step happened thousands of years ago, when meat-eating wolves evolved to tolerate people – and their more starchy, plant-based diet.
