Tips for Feeding Your Dog for a Healthy, Longer Life

Key Takeaways

• Over 59% of dogs are overweight or obese, yet only 36% of owners realize it (APOP data).
• Keeping a healthy weight can add ~2.5 years to your dog's life.
• Choose AAFCO-standard food, provide enough clean water, and feed on a schedule.
• Treats should stay under 10% of daily calories — and know which "human foods" are safe vs toxic.

With so many options — kibble, wet food, home-cooked — choosing the best diet isn't easy. As a veterinarian, I want to share how to screen for the right foods and avoid the dangerous ones, for your dog's health and a longer life together.

1. Feed a Balanced Portion

The Association for Pet Obesity Prevention (APOP) reports that over 59% of dogs are overweight or obese, while only 36% of owners recognize it. That gap means we often underestimate our dog's true weight — harming their health unintentionally.

Calculating portions to match a healthy body weight can extend life by about 2.5 years compared with obese dogs. Ask your vet to help estimate your dog's daily energy needs.

2. Choose Balanced, AAFCO-Standard Food

Dogs need complete nutrition — carbohydrates, fats, protein, vitamins, and minerals. Look for the "complete and balanced" wording and the AAFCO (American Association of Feed Control Officials) statement on the packaging to confirm the food meets international standards (minimums such as 18% DM protein for adults and 22.5% DM for puppies).

3. Clean Water Is Essential

As a rule of thumb, dogs need about 60–70 ml per kg of body weight per day to maintain fluid balance and support kidney function. The exact amount depends on body size, food type (kibble eaters drink more than wet-food eaters), activity level, health, and weather.

4. Build a Feeding Routine

Feeding at the same times each day supports digestion and toilet training. Adult dogs should eat two meals a day because it:

• Stabilizes blood sugar — long gaps can cause lows and frantic, too-fast eating.
• Prevents bloat — large single meals risk stomach distension/torsion, which can be fatal.
• Supports metabolism — energy is spread evenly across the day.

5. Bowl Hygiene

Wash water and food bowls daily to prevent biofilm (bacterial slime) buildup — a breeding ground for germs that can cause diarrhea.

6. Know Which "Human Foods" Are Safe vs Toxic

If your dog accidentally eats something toxic and shows symptoms, see a veterinarian immediately.

7. Strictly Limit Treats

Following animal-nutrition experts (such as the AKC), treats should not exceed 10% of daily calories, to prevent nutritional imbalance and long-term obesity. Most obesity comes down to "calories in excess of need," not any single food type.

Author's Final Note

As a vet, I often see love expressed through "extra treats" quietly become a cause of unintended obesity. Feeding with understanding is the greatest gift of health and time we can give our dogs. Start today: weigh your dog, portion correctly, and you'll share many more healthy years together.
