Sporting dogs are hardworking dogs that need more than everyday nutrition. Eukanuba understands this and developed Eukanuba Premium Performance 30/20 – a food ideal for hunting, field trials and other more strenuous athletic activities in a wide range of environmental conditions. It's packed with 20% more protein and fat to provide sustained energy for peak performance. It also contains natural sources of Glucosamine and Chondroitin Sulfate and as a whole helps maintain healthy joints. Eukanuba Premium Performance 30/20 also contains an appropriate level of highly digestible carbohydrates to help support a short exercise recovery time after sporting activities. Eukanuba Premium Performance 30/20 is nutrient rich to help promote a good nose and scenting ability and contains a special blend of fibers such as beet pulp and FOS (fructooligosaccharides) to promote excellent digestive health.
