Eradication becomes necessary. May need to continue food trial for a longer period of time. We are using the diet to eliminate possible protein allergens. If the itching is controlled after the original diet is changed and then returns when the original protein is added back into the diet, food allergy is diagnosed, and that protein source should never be fed again. If the itching stops during the time the cortisone is being given and never returns the Ivermectin killed the mites and the cortisone broke the itch cycle.
Contact allergy is still a possibility.
If the itch disappears after giving the antibiotics again the diagnosis is confirmed. Keratinazation disorders, skin cancer, and other less common primary diseases will prevent the itch from stopping. Copyright 2000 Tomball Veterinary Clinic.
