Frequently asked questions
How fast should my dog lose weight?
Veterinarians recommend losing 1–2% of body weight per week. For a 60 lb dog, that's 0.6–1.2 lbs per week. Faster weight loss risks muscle mass loss and potential nutritional deficiencies. The Hill's Metabolic formula is clinically calibrated for this rate — the 88% success figure is based on this pace, not crash-diet speeds.
Can I just feed my dog less of their regular food?
Technically yes, but it's not optimal. At reduced portions of regular food, your dog may not receive adequate vitamins, minerals, and essential fatty acids. Weight management formulas are specifically formulated to be nutritionally complete at lower caloric density — your dog gets full nutrition without excess calories.
What's the difference between 'weight management' and 'light' dog food?
'Light' dog food is simply lower in calories — typically 10–15% fewer calories than standard. 'Weight management' food (like Hill's Metabolic) uses a more sophisticated approach: specific fiber blends that trigger satiety hormones (GLP-1 and PYY), reducing hunger at the hormonal level, not just mechanically.
How much exercise should an overweight dog get?
For overweight dogs, start with short 10–15 minute walks twice daily and increase gradually. Swimming is ideal — low joint impact, high caloric burn. Avoid high-impact exercise (jumping, running long distances) until weight is closer to target, especially in larger breeds where joint stress compounds obesity damage.
Do I need a vet's prescription for Hill's Prescription Diet Metabolic?
The Metabolic formula on Amazon is typically available without prescription. The version sold through veterinary clinics is the same formula but may have an official Rx designation. If purchasing online, confirm the formula name matches what your vet recommends.
