Limited information is available regarding the trichographic features of normal canine hair shafts, including those from Dobermanns, with no studies of inter\u2010observer agreement for canine trichographic features.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objectives<\/jats:title><jats:p>To characterize the trichographic features of normal black Dobermann hair shafts evaluating the following variables; gross appearance, primary versus secondary hairs, colour change, tip structure, curling, twisting, bending, cuticle changes (breaks, compression, loss or abnormal overlapping), fractures and variations in hair diameter.<\/jats:p><\/jats:sec><jats:sec><jats:title>Animals<\/jats:title><jats:p>Twenty client\u2010owned, normal, black Dobermanns of different ages and genders.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods and materials<\/jats:title><jats:p>A systemized trichographic evaluation of hair samples from five body locations, which were evaluated independently by two observers, and inter\u2010observer agreement evaluation.

A novel finding of a \u201cround hair tip\u201d was made, which was more commonly found on the dorsal head.
