    TLDR Low testosterone might be a common cause of hair loss in male dogs.
    This retrospective study reviewed medical records of 76 neutered male dogs with hypoandrogenism and alopecia from 1999 to 2017. The most common clinical signs were bilateral symmetrical alopecia starting from the tail to the neck and hyperpigmentation. All dogs had low testosterone levels, and 16 had high estradiol levels. The study concluded that hypoandrogenism, though considered rare, might be more common than previously thought and should be included in the differential diagnosis of symmetrical alopecia in male dogs. Further studies were recommended to better understand these endocrinopathies.
