Dr. De Grasse has found many behaviors and clinical signs in the animal to be altered when the diet is free from the above-mentioned elements. Hyper-activity, dandruff and flaky skin, constant hunger, itching of the skin, reddened eyes, "quick to anger" behavior or angry temperament and wheezing or lung congestion have all been either reduced or removed in the animal.
