Hi Amy H!
How were your pup’s allergies determined? Most allergy tests are not reliable and most dog allergies are usually environmental, not food related.
That being said, the best way to determine food allergies is by an elimination diet. An elimination diet might be started with a novel protein or a hydrolyzed Rx food to clear the system and then slowly adding in a new protein one at a time to determine a possible allergy.
Glad you are not feeding Orijen any longer. It along with Champion’s other formulas are some of the most that are correlated with dilated cardiomyopathy. Mars is a great dog food manufacturer. They employ experts, own their own manufacturing plants, do a ton of research and perform feed trials.
Best of luck to you figuring this out!
