Description
Summary:	The establishment of the possibility of using pattern of dog’s nasal speculum for individual biometric identification has prompted further research in this area. This research was aimed at studying and searching general characteristics of papillary pattern details of dog’s nasal speculum in order to use it in practice of forensic veterinary identification of individuals of this species. In the furtherance of this goal, we examined nose prints of 266 dogs of different species, ages and housing conditions. In the course of the research, we took into account, recorded and classified characteristics that are observed in all species of the canis familiaris family. Thus, it was found that nose prints contain information on the severity of nose’s symmetry line, its form, the presence of symmetry line branches of the nose and fine lines, as well as density of the print by papillary pattern and shape of the print. Experimentally, it has been established that the nose symmetry line can be well and weakly expressed; 8 types of lines of symmetry of the nose were determined: straight, fusiform, wedge-shaped, straight round-ended, round-ended wedge, V-type form, disrupted and complex; the impression may be present or absent branches of the nose symmetry line; the impression may be unspotted, weakly spotted or heavily spotted with fine lines; 2 basic impressions were found and it was revealed that impressions may have different density of papillary pattern.
