There is no universal rule. Meal frequency depends on your dog's age, breed, activity level, health, and food type.
General Recommendations
• Puppies: 4–6 meals per day until about 6 months old.
• Adult dogs: 1–2 meals per day is most common.
• Senior dogs: may benefit from 2 meals, smaller portions, or even 3 meals if they eat slowly.
Consult your veterinarian and observe your dog's appetite, weight, and energy to determine the best schedule.
