It's for my dogs very important to remain in good condition. Not so you become world champion. In such high level training asks very much of a body. An animal that has to  deliver top performances recuires an  extremely selected food. That is why I give the super rich energy chunks of Brit-Petfood (4382 kcal)Even in the depths of winter and after the  extreme hard training months the dogs remain well on weight and look radiant! In short, a great sport food! My dogs can not work without Brit-Petfood!
