I’ve been using Orijen 6 fish for several years due to some kind of allergy, never did pinpoint it, that was causing ear infections. The fish formula was recommended since often times it’s one of animal meats that the dog is allergic to. Been working well for us. But with three high energy dogs between 50 - 70 lbs, it’s quite a feed bill.
We have also used the Orijen 6 fish..... he likes the red better.
We simply have to stay clear of chicken , grain and grasses. We went through the blood test garbage... grrr $$$. Falco had the ear infections and hotspots. At present they are mostly controllable... we also bathe him once a week with a medicated shampoo.
I hate going through all of this stuff, but he’s much more comfortable and I consider it my responsibility to do the best for my good friend.
