You can just gnaw on dog treats if you want. Like nobody is stopping you. My parents tried and failed many many years ago, but the sandy texture of the treats they bought was a major turnoff for me, so no need fam. If dentabones or whatever had been a thing back then I might have a different story..

Fun fact; most pet foods and treats are tested at some stage by humans for flavor, because animals can’t really give proper critique. So someone, somewhere, has probably already eaten them.
