Over 50% of dogs in the UK are currently classified as overweight or obese, placing severe strain on cardiac health, respiratory function, and arthritic joints. Under veterinary clinical guidelines, safe canine weight loss requires restricting dietary fat (<10–12%), increasing therapeutic crude fibre (5–8%) to maintain gastric satiety, and supplementing L-carnitine to accelerate fat oxidation while preserving lean skeletal muscle.

Macronutrient Breakdown: Satiety & Lean Muscle Preservation
Low-fat diets should never simply cut protein—doing so forces the body to catabolise its own muscle tissue. Instead, fat is strictly limited to 7–10%, while lean protein and complex prebiotic fibres maintain metabolism.
Ideal Weight Loss Macronutrient Split (Dry Matter)
L-Carnitine supplementation transports fatty acids into mitochondrial membranes, turning stored adipose tissue into active energy.
