The prevalence of sensitization to dogs and cats varies by country, exposure time and
predisposition to atopy. It is estimated that 26% of European adults coming to the
clinic for suspected allergy to inhalant allergens are sensitized to cats and 27% to dogs.
This document is intended to be a useful tool for clinicians involved in the manage-
ment of people with dog or cat allergy. It was prepared from a consensus process
based on the RAND/UCLA method. Following a literature review, it proposes various
recommendations concerning the diagnosis and treatment of these patients, grounded
in evidence and clinical experience. The diagnosis of dog and cat allergy is based on a
medical history and physical examination that are consistent with each other and is
confirmed with positive results on specific IgE skin tests. Sometimes, especially in poly-
sensitized patients, molecular diagnosis is strongly recommended. Although the most
advisable measure would be to avoid the animal, this is often impossible and associ-
ated with a major emotional impact. Furthermore, indirect exposure to allergens
occurs in environments in which animals are not present. Immunotherapy is emerging
as a potential solution to this problem, although further supporting studies are needed.
