I would indeed stay away from common ingredients, particularly chicken, lamb, and beef. However, I would dump the Royal Canin as soon as possible. Your vet probably put your dog on it as it doesn’t contain any meat/animal-based protein, which is fine as that should allow your dog to heal up from the allergic reaction. But I would NOT feed it long-term, since dogs should be fed meat.
You can search the 5 star foods here at DFA, then weed out the ones that contain chicken. Some may not be available in your area, but you can always find places on the net to buy it for little or no shipping cost.
If you have questions about specific foods, then feel free to ask. But make sure to put it in the proper forum, so that way it’s seen by more people.
And FYI, here are a few I’d suggest if you were in my store, as they are grain free and don’t contain any chicken, lamb, or beef…
Merrick Grain Free Duck or Pork
Zignature Trout & Salmon or Turkey
Acana Pacifica
