Pets can be \"allergy friends\" through mechanisms related to hygiene hypothesis and translational aspects, the dual role of IgG4 antibodies for pets, and their promising role as healthcare service animals (dogs). On the contrary, animals can be \"allergy enemies\" when inducing allergic sensitization and  respiratory symptoms (sometimes leading to severe reactions), and also due to cross reactivity with other pets allergens, indirect exposure and ubiquity of their allergens, cross reactivity between Can f 5 and human prostate-specific antigen (PSA). Moreover, in some cases they can trigger anaphylaxis, induce occupational asthma, and act as pests. Finally, we must outline the modest efficacy of allergen immunotherapy (AIT) for their allergens. From a strictly allergological perspective, it is evident that the \"negative\" aspects resulting from exposure to domestic / non-domestic animals outweigh the \"positive\" aspects.

This exploratory study aimed to characterize the quantity and avidity of autoantibodies against IgE and FcεRI over 6 months. <b>Methods.</b> The serum of 49 patients with CSU and 30 healthy control subjects was obtained at baseline and 6 months.
