We have Canyon Creek Ranch duck tenders, which are just like jerky made from duck breast fillets. We also have Yummy Chummies Gold Salmon treats, which are 95% salmon, they are grain free and have glucosamine and chondroitin for joints. The Salmon ones do have some potato, but neither of mine have issues with it. They also love string cheese, baby carrots, blueberries, and pretty much everything else that fits in their mouths. lol (the string cheese does give Frankie bad gas though)
Bravo makes a freeze dried venison liver that is cut in small cubes. Also, a product called Salmon Paws is great too. I have to be careful because Lucy is allergic to lots of stuff. Like others Lucy gets carrots and apples too.
