My Lexi has severe allergies and her first allergic reaction was to RC. It has corn in it and MANY dogs are allergic to corn. Also it can take anywhere from a couple days to a few months for food allergies. It will probably take a few months to get back to normal if you switch her food back.
I could go on for hours about food allergies. My baby has been in and out of vets to the hospital. She has had 3 alleergy blood test done and 3 skin test. She now gets a shot once a week. |
