Plain-English summary
A group of dogs with atopic dermatitis (a skin allergy) was studied to see how indoor house dust mite levels affected their symptoms. The research found that dogs living in areas with higher humidity and near green spaces had different levels of dust mites, which seemed to influence their skin condition. Interestingly, higher dust mite levels were linked to better skin barrier function, suggesting that living in a healthy environment might help improve skin issues. More research is needed to fully understand this relationship, but it indicates that where you live could impact your dog's skin health.

Abstract
IntroductionHouse dust mites (HDM) are regarded as essential environmental allergens not only in human, but also in canine atopic dermatitis (CAD), however, there are only a few studies on the influence of indoor HDM concentration on the disease.MethodsOur study analyzed the correlation between the indoor HDM concentration, the severity of CAD, and the residential environments in client-owned 35 AD and 13 healthy dogs. We measured the extent of CAD and severity index-04 (CADESI-04), pruritus visual analog scale (PVAS), and transepidermal water loss (TEWL), indoor relative humidity (RH) and analyzed the residential environment questionnaires to evaluate AD severity.ResultsThe Der f 1 concentration had an inverse association with TEWL, and no association with CADESI-04 and PVAS. The Der f 1 concentration was significantly high in the group living near the green area and 40% or higher RH.DiscussionOur results suggest two possibilities: (1) Living around green areas and maintaining an appropriate indoor climate may help to improve CAD clinical symptoms. (2) The HDM may contain endotoxin and when present in high concentrations in CAD, they play a preventive role by enhancing the skin barrier function. Further studies with a larger number of dogs may help further elucidate an association between CAD and Der f 1.
