The thymus generally presents as a sail-shaped soft-tissue opacity on thoracic radiographs in young, pre-pubescent dogs. After puberty, lymphatic tissue is replaced by adipose tissue and can usually no longer be identified on radiographs; however, thymic remnants have often been observed in adult dogs. The objective of this retrospective descriptive study was to investigate the incidence of thymic remnants using thoracic radiographs and to analyze the incidence in dogs by age, sex and breed. We analyzed the data from 1,464 dogs that underwent both thoracic ventrodorsal and right lateral radiography, of which 40 underwent both radiography and computed tomography (CT). …

In horses and cattle, hair whorls have been shown to act as a structural marker of reactivity and behavioral lateralization. Few studies on canine whorls have been reported and none have assessed whorl position or direction of flow. This study describes the distribution and characteristics of whorl in each of 10 regions in which whorls are typically located in dogs. Hair whorls were assessed in dogs (n = 120) and were recorded as clockwise or counterclockwise in the cephalic, cervical (dorsal, lateral, ventral), thoracic and brachial axillary, chest, shoulders, elbows, abdominal, and ischiatic regions. Bilateral whorls, including brachial axillary, elbow, …

Hair whorl characteristics were assessed in the domestic dog (Canis familiaris) in the regions of cephalic, cervical (dorsal, ventral, and lateral), thoracic and brachial axillary regions, the chest, shoulders, elbows, ventral abdominal region, and on the caudal thighs (ischiatic). They were classified as simple or tufted, and their position was recorded as the distance between their centers and bony landmarks within each region. The distribution of whorls was explored in a cohort of domestic dogs (N = 120) comprising a variety of breeds and cross‐breeds, sourced from shelters (N = 60) and the general public (N = 60). …
