The description of age and local features of lymphatic capillaries of the stomach in dogs is pro-vided in the study. Research was carried out at the Khakass State University named after N.F. Katanov. The material of research were mongrel dogs (n=58) of five age groups: newborns, weaning period, puberty period, physiologically mature and the period of expressed senile changes. During the research methods of an interstitial injection of the lymphatic course by dyes, production of painted total preparations from lymphatic capillaries, pro- duction of brightened-up preparations from the wall of the stomach, histological cuts, light and electron-ic microscopy, morphometry were applied. It was established that lymphatic capillaries were roots of intraorganic lymphatic course of all covers of the stomach in dogs. Being weaved among them-selves, and also with lymphatic post-capillaries, they form uniform multi-plane lymph microcirculato-ry channel which tectonics has specific, age and local features and is caused by morphological and functional features of stomach covers. In the struc-tural relation the wall of lymphatic capillaries of the stomach in dogs is presented by a unary layer of endotheliocytes. Morphometric indicators of lym-phatic capillaries of the stomach in dogs increase in post-natal ontogenesis in direct ratio to age of an animal.
