Concept for Life Medium Light is a tailored, premium dry dog food designed specifically for overweight, adult medium‑breed dogs aged 12 months and over. With its balanced, reduced‑calorie formula, this kibble helps your canine companion achieve and maintain an ideal body weight while providing all the essential nutrients for long, healthy living.

The foundation of a long, healthy life for your dog is species‑appropriate, balanced nutrition. Adult dogs often gain weight due to reduced activity or unsuitable diets, increasing the risk of serious health issues. By addressing early signs of weight gain with exercise and a low‑fat, low‑calorie diet, you can keep your medium‑breed adult dog in optimal shape.

Concept for Life Medium Light delivers precisely that: a balanced diet engineered to meet the unique needs of overweight dogs and those prone to weight gain. Its formula is crafted to support all‑round health, from muscle maintenance to joint resilience.

Beyond exercise, this kibble’s reduced energy content prolongs satiety through added psyllium and lignocellulose fibres. High protein levels help preserve lean muscle mass, while a 15% calorie reduction (vs. Medium Adult) keeps weight in check. The proprietary FORMULA X further promotes lifelong wellness.

The premium meat base, combined with functional ingredients, creates an easy‑to‑digest, highly accepted kibble. The vitamin‑B complex, copper, zinc, and omega fatty acids work synergistically to maintain a glossy coat and supple skin, while the Stay‑Clean™ complex combats plaque and tartar buildup.

Concept for Life is a scientifically grounded nutritional approach that adapts to your dog’s life stage. Medium Light provides a complete, balanced diet for medium‑breed adults.
