FAQs
How many cups of food should I feed my dog per day?
It depends on weight and the calorie density of your food. A 50 lb adult dog needs roughly 2.5 cups of standard dry kibble (~380 kcal/cup) per day. Always check your specific brand’s label and adjust based on monthly weight monitoring.
Should I feed my dog once or twice a day?
Twice daily is recommended for most adult dogs. Puppies need 3 meals per day. Twice-daily feeding reduces bloat risk in large breeds and helps you monitor appetite changes more easily.
