Obesity Prevention | Healthy Pets, Healthy Families Hub | Veterinary Public Health

Obesity is a major health issue in the U.S.—and our pets are following in our footsteps. An estimated ~50% of dogs and cats are overweight or obese.

Research suggests there may be a link between obesity in humans and dogs—we often share habits. The upside: pets can also help people be more active.

About 50% of people in LA County are considered overweight.
Major causes of pet obesity mirror people: too little exercise and improper diet (e.g., free‑feeding encourages overeating).
Many owners don’t recognize when a pet is overweight — if you can’t feel ribs, it’s time to adjust feeding.
Obesity increases risk for diabetes, arthritis, and heart disease in people and pets.

Talk to your veterinarian about healthy weight and diet for your pet.
Feed appropriately:
- Consult your veterinarian before starting a weight‑loss plan for your pet.
- Don't give your pet table scraps and people food.
- Measure portions; follow the label as a starting point and adjust with your vet’s guidance.
Exercise together:
- Check with your vet first before beginning an exercise plan.
- Goal for dogs: about 30 minutes of moderate activity daily (adjust per your vet).
- Walking, jogging, or hiking with your dog can help both of you stay healthy.

We promote awareness of animal obesity—helping owners recognize when pets are overweight and how to take action.
