My rottie just passed last month from lymphoma. When he was eating kibble he did really well on Acana Regionals. There are 4 grain-free varieties. Orijen is another great food made by the same company that makes Acana. Other grain-free foods we tried and liked were: Annamaet grain-free, Horizon Legacy, Go! Fit & Free Adult, and Earthborn Holistic Primitive Natural. Others I like but haven’t tried personally are Dr. Tim’s Kinesis grain-free and Victor grain-free.
Sometimes dogs eating kibble (and especially older dogs) can benefit from probiotics and digestive enzymes. I buy mine from swansonvitamins.com. They’re made for humans and pretty cheap. I get the regular Swanson brand digestive enzymes and Dr. Langer’s 15 strain probiotic (they’re buy 1 get 1 free right now). I crush the enzyme tablet and open the probioic capsule and mix it up in the food. You can add a little canned food, yogurt, canned pumpkin or something else so it is not just powder mixed with dry food. My almost 8 year old Great Dane is super regular and not very gassy at all. He doesn’t eat kibble but he gets probiotics and enzymes. A lot of people also like the Mercola pet enzymes and probiotics. They are more expensive but they are already in a convenient powder form.
Hope this is helpful to you.
