The Pet Obesity Epidemic

The Association for Pet Obesity Prevention reports that 59% of dogs and 61% of cats in the U.S. are overweight or obese. Excess weight is now the #1 preventable health risk in pets — reducing lifespan by an average of 2.5 years. Yet most owners don't recognize their pet is overweight. A landmark Purina study proved that dogs maintained at an ideal weight lived nearly 2 years longer than their overweight littermates. The good news: even modest weight loss (6–8% of body weight) produces measurable health improvements.

Health Risks of Excess Weight

Overweight pets face significantly higher risk of: osteoarthritis and joint disease (the #1 consequence — excess weight accelerates joint deterioration), diabetes mellitus (cats are 4x more likely when overweight), respiratory compromise, heart disease, urinary tract disease, certain cancers, decreased immune function, heat intolerance, skin infections in skin folds, and anesthetic complications if surgery is needed. Every extra pound on a cat is equivalent to approximately 15 extra pounds on a human.

Is My Pet Overweight? Body Condition Scoring

At ARCH Veterinary, we use a 1–9 Body Condition Score (BCS). Ideal is 4–5 out of 9. You should be able to easily feel (but not see) your pet's ribs. There should be a visible waist when viewed from above and an abdominal tuck when viewed from the side. If you can't feel ribs without pressing firmly, or there's no waist/tuck, your pet is likely overweight. Our veterinarians will assess your pet's BCS, calculate their ideal weight, and design a customized weight loss plan.

Why 'Just Feed Less' Doesn't Work

Simply reducing portions of regular food can lead to nutritional deficiencies — your pet gets fewer essential vitamins, minerals, and protein along with fewer calories. Prescription weight management diets (Hills Metabolic, Royal Canin Satiety) are specifically formulated to: reduce calories while maintaining complete nutrition, increase fiber for satiety (so your pet feels full), and support muscle mass preservation during weight loss. Safe weight loss rate: 1–2% of body weight per week for dogs, 0.5–1% for cats.

ARCH Veterinary Weight Management Program

Our program includes: initial assessment with body condition scoring and ideal weight calculation, metabolic bloodwork to rule out thyroid disease or other medical causes, customized calorie calculation and feeding plan, prescription weight management diet recommendation, exercise prescription appropriate for your pet's condition, monthly weigh-ins and plan adjustments, and ongoing support and troubleshooting. We've helped hundreds of San Jose pets reach their ideal weight — and their owners report dramatic improvements in energy, mobility, and quality of life.

Frequently asked questions

How can I tell if my dog or cat is overweight?

You should be able to easily feel your pet's ribs without pressing hard, see a defined waist from above, and notice an abdominal tuck from the side. If any of these are absent, your pet is likely overweight. Your ARCH vet can provide an objective Body Condition Score assessment.

How much should I feed my pet to lose weight?

This varies significantly by pet — never guess. Your ARCH veterinarian will calculate the exact calorie target based on your pet's ideal weight, current weight, and activity level. Most pets need 20–30% fewer calories than the bag feeding guidelines suggest (which are designed for active, intact animals).

Is it safe for cats to lose weight quickly?

No — rapid weight loss in cats (more than 1–2% body weight per week) can trigger hepatic lipidosis (fatty liver disease), a life-threatening condition. Cats must lose weight slowly and steadily under veterinary supervision.
