My dogs LOVE this kibble!They are going on 3 and 4 years old. One of my dogs is grain sensitive and used to have non-stop rashes and itchy skin before I switched to this diet. Since I switched to the diet outlined below they haven't had a day sick, a single tummy upset or a skin rash. I also struggled with them being a bit too heavy. I didn't want to cut them down any more because they were SO hungry. I rotate my dogs through the various flavors. My vet said that it is best not to rely on one protein source as dogs may get food sensitivities and/or bored with it.I used to buy the Orijen Arcana but don't anymore because it is lower protein. I give my dogs fresh produce (fresh raw chopped vegetables once a day, and tiny quantities of fruit (I always check what dogs can and cannot have before giving them any produce) so they don't need the higher percentage of dried fruit and vegetables included the Arcana kibble.I also mix this kibble with Primal raw frozen nuggets so they get fresh meat with every meal, and they get one raw meaty bone each week (I buy the Primal bones from Pet Club). I felt weird about giving them dry kibble alone as that might be convenient for us, but I feel that it would be like us eating protein/energy type bars for every meal. I strongly feel that dogs (and humans) need fresh,raw ingredients too.I also give my dogs a spoonful of lactose free (a lot of dogs can't digest lactose) plain yogurt with one meal a day. One of my rescues came to me with a yeast infection due to the gross diet (you don't want to know) she was subjected to, at the very shonky "rescue" place. Our vet put her on a couple of courses of probiotics and recommended I give her yogurt each day to cure the infection. They both loved it so I saw no reason to stop. The probiotics and calcium can only be a good thing in my opinion, and if I run out they sit by thier bowls waiting after they eat, 'cause they know its missing!For treats I give them Canidae Grain Free dog treats as they are very low calorie, small, firm, chewy treats that can be put in your pocket without them disintegrating during a walk or training.It took me a lot of time to sort out what worked best for us. I am not an expert, but my dogs love thier food and my vet says that they are in perfect health and at the perfect weight, and that thier diet couldn't be better, so perhaps this info might help someone put together a complete diet for thier dog.Here is what I feed them twice a day:All dogs are different, but my 18lb dog (who was a slightly overweight 21lb dog before this diet) gets:- 1/4 cup Orijen kibble twice a day.-1 thawed primal meat nugget twice a day. I rotate through the various Primal Frozen meat nuggets. You can also buy these freeze dried and reconstitute them with water but I prefer giving them the raw primal nuggets. In the morning I add a spoonful of plain lactose-free yogurt to thier dishes. And in the evening I add about 1/4 cup produce instead of the yogurt. Generally a mix of two items - either chopped green beans, cucumber, broccoli, carrots, cooked squash (I use canned organic non-sweetened, plain - beware pie pumpkin with spices) red, yellow, green peppers, a little romaine, other leafy greens - sometimes a couple blueberries, pieces of apple, orange, pineapple, melon etc.My 11lb dog gets exactly the same except she gets a bit less than half of of the kibble that I give 18lb dog at each meal.Once a week I give them thier dinner minus the primal frozen nugget and then give them a raw meaty or marrow bone which they gnaw on for hours. It helps clean thier teeth too.Hope this info is of use to someone. If so, please click "helpful" as I spend a lot of time on my reviews hoping to perhaps help someone, and I also believe in supporting great products! I am happy to answer any questions. I couldn't be happier with the quality of this kibble.
