This James Wellbeloved Lamb and Rice Senior Dog food is ideal for dogs over 7 years old. This is complete dry food with the bonus that it is hypoallergenic. With selected protein source lamb and selected carbohydrate sources of rice and barley, it is a dietetic food, excellent for the reduction of ingredient and nutrient intolerances. We suggest that the food be tried for a period of 3 to 8 weeks. If the signs of the food intolerance disappear, continue feeding indefinitely. This dog food provides support for heart, joints and the immune system with added taurine for the heart; chondroitin, glucosamine & herbs for joints and higher levels of Vitamins C & E for immune system.
