Obesity in dogs and cats
Obesity is the most prevalent nutritional disease in modern pets, more common than any hereditary condition. WHO Animal considers it a pandemic. Obese pet isn't 'chubby cute' — is sick. Good news: 100% reversible with correct management.
🚦 Urgency triage: yellow vs red flag
🟡 Yellow flag — monitor / vet in 24-72h
- body score 4/5 / fatigue on short walk
🔴 Red flag — emergency NOW
- dyspnea at rest / unable to lie down or stand
How to identify (Body Condition Score)
BCS goes from 1 (very thin) to 9 (obese). Ideal: 4-5.
- BCS 5 (ideal): you feel ribs without effort, visible waist from above
- BCS 6-7 (overweight): ribs with difficulty, no defined waist
- BCS 8-9 (obese): don't feel ribs, rounded belly, visible fat at tail base
Health risks
| Disease | Risk vs. ideal weight | Impact |
|---|---|---|
| Type 2 diabetes | 4x greater | Requires lifelong daily insulin |
| Arthritis | 3x greater | Chronic pain, immobility |
| Kidney disease | 2.5x greater | Reduces expectancy by 3 years |
| Cancer | 2x greater | Mammary, prostate, intestine |
| Heart disease | 3x greater | Heart failure |
| Pancreatitis | 5x greater | Veterinary emergency |
| Surgery at risk | 2x greater | Anesthesia more dangerous |

Frequently Asked Questions
Is my pet chubby or obese?
Check the Body Condition Score. If you can't feel ribs when lightly running your hand, it's overweight (BCS 6+). If you can't see a waist from above, it's obesity.
Can I fast my dog to lose weight?
No. Fasting doesn't cause weight loss — slows metabolism and causes muscle loss. Correct weight loss requires ADEQUATE and frequent feeding.
How long does it take for a pet to lose weight?
Safe goal: 1-2% of body weight per month. A 10kg pet with 3kg overweight takes 6-12 months to reach ideal weight safely.
Does light food work?
Partially. 'Light' food is less caloric but still allows weight gain if given in excess. Better: therapeutic weight loss food prescribed by vet.
My dog is constantly hungry, what to do?
Increase meal frequency (same total per day, more times), use slow feeders and add fiber (carrot, broccoli) that provide satiety without calories.
