Treatment results can give a lot of valuable information for the formulating of an exact diagnosis. Clients need to have enough information at the beginning of the treatment to become a partner with the veterinarian against the pets offending environmental problems. Clients must become educated enough to use the several wonderful weapons that can be brought to bear in the fight to eradicate fleas. If the pet is allergic to fleas one or two fleas may be able to create the problem. Control will not solve the problem.
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.
