My mom used to own a grooming shop, and sold jerky for dogs. Two of the groomers there preferred it over jerky for humans, and would routinely be found snacking on it. I've tried it, it's basically just jerky without the pepper. I like the pepper, so I prefer regular jerky. Lol.
We also make our own dog food, though, and it's basically rice veggies and turkey (sometimes chicken livers). Which is, honestly, something I would totally go to town on, if it were just seasoned a little better
Ooh, I might pick up some salmon for them, they'll like that. We do mackerel sometimes, too. And once or twice we've done just ground beef because I forgot to shop until 930 at night and dollar general sells it lol
