This kibble is designed for boxers older than 15 months and it promises to maintain muscles, protect joints, support heart muscles and help with optimal digestion and nutrient intake. Royal Canin took Big Ben’s unique head shape into account, with it’s short face and underbite. Did you know your boxer likes to suck his food before he eats it? And did you know that like all large dogs, a boxer’s stomach is rather sensitive – more so than with smaller breeds? Royal Canin does and that is why their kibbles are so successful. This complete diet contains L-carnitine, taurine, EPA and DHA for optimal health and cardiac function. The antioxidants in the formulation supports longevity.
