The present investigation was carried out in order to study tear production in dogs using the Schirmer test in the province of Bolívar, Ecuador. Wherefore, 394 samples were taken at random, in the 7 cantons of the province. A previous analysis of the different cantons to visit was carried out, to determine where there was a higher concentration of dogs, from which samples were to be taken. Once the patients had been identified, the medical file was filled out, which contains the owner's data, dog data, date, place, physiological constants, and data on the production of each right and left eye. After a previous evaluation, where the animal's state of health is considered, the tear production of each right and left eye was quantified for one minute. With the research work carried out, it was possible to establish tear production values in dogs in the evaluation area. Through the statistical analysis, different tear production values were determined according to the shape of the skull, according to age, and according to the right and left eye. It could be concluded that the Schirmer test, is a simple and an effective diagnostic method to determine the degree of tear production in canines.
