Our dogs also have allergies, and if I may say chicken and turkey are huge allergens for alot of dogs[:D] Mine included. We use Timberwolf ocean blue and absolutely love it!!  the shipping is free, or how ever you want to "state" it. Their allergies are so bad it's really the only foods they can tolerate, and any rotation will come with alot of time, one of my girls has colitis and can't tolerate that.  Good luck, please keep us posted!!
