Plain-English summary
A group of Chesapeake Bay retrievers was brought in for hair loss that was not itchy or inflamed, affecting specific areas of their bodies. Tests showed that seven of the dogs had higher levels of certain hormones, which may be linked to their condition. A closer look at their skin revealed changes in hair follicles and hair structure. This hair loss appears to be a breed-related issue that affects young adult Chesapeake Bay retrievers, and it may be influenced by genetics. While there is no specific treatment mentioned, understanding the condition could help in managing it better in the future.

Abstract
Ten Chesapeake Bay retriever (CBRS) dogs with hair loss were recruited in collaboration with the American Chesapeake Club. All dogs had nonpruritic, noninflammatory, regionalized hair loss affecting the same areas of the body in male and female dogs. Hormonal investigations showed increased adrenal and sex steroid concentration in seven cases. Histopathology revealed follicular hyperkeratosis and plugging, follicular atrophy, and occasional melanin clumping with malformed hair shafts. This study suggests that hair loss in CBRS is a breed syndrome in which young adult dogs have hair loss characterized by unusual histological features and abnormal steroid production. A familial predisposition seems likely and selective breeding might reduce the occurrence of this condition.
