Adverse food reactions may accompany atopic dermatitis, therefore it is advisable to undertake a strict dietary trial first. Eliminate any other causes of pruritus for example fleas, parasitic, bacterial and yeast infections. Avoidance where possible of positive indoor/outdoor allergens. If no or partial response is seen, then an allergen–specific immunotherapy treatment may be selected.


This is a bespoke allergen specific therapy, available for cats, dogs and horses. Immunotherapy is a desensitizing therapy specific to the SENSITEST® test results and targets the root cause of allergy providing long term relief to symptoms.
