The article presents data on the dynamics of the comparative number of neutrophils, their ability to phagocytosis and the main populations of immunocompetent cells in terms of estrus in female dogs. Comparing the dynamics of the quantity of neutrophils with their phagocytic activity, it should be noted that the percentage of active neutrophils had the opposite trend. Thus, during the follicular phase of the sexual cycle, namely from days 1 to 15, the number of neutrophils capable for phagocytosis significantly increased from 60.0±3.09 to 65.333±4.52 (P ≤ 0.05). The dynamics of the comparative number of lymphocytes and their regulatory subpopulations per estrous shows that from days 1 to 10 (the follicular phase of the estrous cycle) there was a significant (P ≤ 0.05) decrease - by 2.7%. In our experiment, the number of monocytes had a constant tendency to increase, regardless of the phase of the sexual cycle. It has been determined that during ovulation the number of natural killers decreases, while the number of T- and B-lymphocytes, on the contrary, increases.
