Flea infestations cause significant welfare harm through itching, allergy, and secondary infections. Modern preventive treatments make this suffering almost entirely preventable.
Flea-related suffering is almost entirely preventable with modern parasite control yet remains common because of inconsistent prevention use. Animals with flea allergy dermatitis experience chronic itching and skin infection that significantly compromises welfare. Year-round preventive treatment combined with environmental control eliminates this preventable suffering. Cost-effective prevention options are available for owners at various income levels.
