Mapping the canine skin: a study of coat relative humidity in Newfoundland dogs

Abstract An instrument is described which uses air aspirated via a narrow probe from an animal's hair coat to assess the relative humidity (RH) of air within the coat. This was used to investigate regional differences in coat humidity in a group of 21 Newfoundland dogs maintained in a constant...

This was used to investigate regional differences in coat humidity in a group of 21 Newfoundland dogs maintained in a constant environment of 40%RH. At sites over the rump, mid‐lateral thigh and chest wall, the coat RH was about 50%, whilst beneath the tail and on the ventral neck the RH was about 70%. It was observed that at tail and neck sites the RH rose with increasing age of the subject. No differences were observed related to the coat colour or sex of the subjects, but coat type was relevant. The relative humidity of finer coats on exposed sites was about 7% lower than those of normal coats. The physical features affecting these findings, i.e. convection, conduction and the effect of matting, are discussed, together with the implications for microbial colonization. Résumé— Un instrument qui utilise à l'aide d'une sonde étroite l'air aspiréà partir du pleage pour mesurer l'humidité relative (HR) du pelage est décrit. Celui‐ci a été employé pour déterminer les différences régionales de l'humidité relative dans un groupe de 21 Terre Neuves maintenus dans un environnement constant à 40% d'humidité relative. L'humidité relative est de 50% sur les membres, les faces internes des cuisses et le thorax, tandis que sous la queue et le cou, elle est de 70%. Il a été observéégalement qu'au niveau de la queue et du cou, l'humidité relative augmente avec l'âge. Aucune différence n'est notée en function de la couleur du pelage et le sexe des animaux.
