A harnessing assembly for animals includes a strap. Each of a pair of connectors is coupled to the strap. The strap is couplable to each connector to form a pair of first loops. Each of a pair of first fasteners is slidably coupled to a respective first loop. A coupler is coupled proximate to a midpoint of the strap. The coupler is configured to couple to a leash. Each of a pair of strips is coupled to and extends from a front edge of the first strip, bracketing the coupler. A pair of second fasteners, which is complementary to the first fasteners, is coupled singly to the strips distal from the front edge. Each second fastener is positioned to couple to a respective first fastener to form a second loop. Each second loop comprises a respective first loop, such that the second loop is adjustably sizable.
