But, first of all, the level of sports results, as well as the ability to withstand intensive training and withstand many shots, change of direction, touchdowns and turns, characteristic of agility competitions, disk dogs or canicross, depends on the health of his joints. Perhaps played on land that is not favorable (dirt, synthetic or hard soils). In addition to assessing the overall physical “shape”, one of the “primary health needs” of sporting dogs, therefore, is to support the joints, maintain their physical and functional integrity for as long as possible, and facilitate their quick recovery between maintenance and the other during training. The risk that should be avoided The risk is that if they are not adequately protected from numerous and prolonged mechanical stresses, these important organs of movement deplete their energy and m
