Plain-English summary
A group of poodles was examined for changes in their hair follicles that can happen with age or certain health issues. Researchers found that while these changes are common in poodles, they aren't always linked to calcium buildup, which can be a sign of other conditions like Cushing's disease. This means that not all poodles showing these changes necessarily have a serious problem. A special test is needed to confirm if calcium is present.

Abstract
BACKGROUND: It is commonly accepted that canine dystrophic mineralization of the hair follicle glassy membrane can be seen in hyperadrenocorticism and as a senile change in poodles. Pathology textbooks define this change as deposition of calcium salts in the form of basophilic, amorphous, granular material along collagen fibrils. HYPOTHESIS/OBJECTIVES: The aim was to evaluate whether the incidence of the lesion is specific to poodles and if it is always associated with calcium deposition. ANIMALS: One hundred and forty-seven dogs divided into three groups: (i) 91 normal poodles; (ii) 40 dogs of other breeds; and (iii) 16 dogs with clinical/histopathological diagnosis of hyperadrenocorticism. METHODS AND MATERIALS: Retrospective study; with haematoxylin and eosin, and von Kossa staining. RESULTS: Our findings demonstrate that perifollicular changes of the hair follicle glassy membrane of poodles are not always associated with calcium deposition. CONCLUSIONS AND CLINICAL IMPORTANCE: A specific staining is needed to identify true calcium deposition when performing histological examination of the skin of poodles.
