Allergies in dogs have become a relatively frequent topic of discussion in veterinary surgeries. Many dogs, both purebred and of mixed breeds, are diagnosed for allergies. Allergies have many causes, from genetic predisposition to the environmental conditions in which the animal lives. Allergies in dogs are troublesome because they can lead to serious health complications when diagnosed late or left untreated. The results of the study support the hypothesis that the percentage of allergies to individual allergens varied by region (Tab. 4). Differences were observed in the case of Dermatophagoides pteronyssinus and Dermatophagoides farinae house dust mites, Acarus siro, and Tyrophagus. The remaining allergens caused allergic reactions in similar percentages of dogs from northern, central and southern Poland.
