Skinners Field & Trial Maintenance Plus is a complete working dog food. This dry food recipe has been developed to support dogs with a low to moderate activity level who might benefit from additional nutrients to support their joint health. Maintenance Plus is also suitable for dogs with a reduced activity level, or those prone to weight-gain on some of our other working dog formulations. This product will also suit dogs who might be resting or recovering out of season and so do not require an energy dense feed but again, will benefit from the inclusion of Joint Aid. Maintenance Plus has been formulated with a protein level (18%) and fat level (11%) to support normal day-to-day activity and provides everything your dog requires to remain happy and healthy, as well as providing nutrients that can help support joint health and integrity.
