Overweight dogs should consume fewer calories, while underweight dogs may need a higher intake to reach a healthy weight.
Feeding your dog the right amount depends largely on their size, weight, and activity level. General feeding guidelines for small, medium, large, and giant dogs are based on an average caloric content of 350-400 kcal per cup of dry food. Adjust portions based on your dog's specific needs and consult a veterinarian for personalized recommendations.
Puppy food is more complex since their nutritional needs change as they grow. Puppies require extra calories, protein, and nutrients for development. As they near adulthood, their diet should gradually transition to an adult feeding routine.

Senior dogs have different dietary needs as they age. Veterinarians generally classify dog breeds as seniors at the following ages:
Lifestyle and overall health also affect feeding requirements. Many senior dog foods have lower calorie content to maintain a healthy weight as activity levels decrease. Some formulas include joint-supporting ingredients or help manage age-related conditions.

Feeding guidelines may vary based on your dog’s metabolism, activity level, and specific health conditions, so always consult your vet for personalized recommendations.
Feeding a healthy adult dog is straightforward since their nutritional needs remain stable unless their lifestyle changes.
The key factor is weight. Use your dog’s body weight per day—not necessarily their current weight—to determine the correct portion. If they are overweight, feed them slightly less; if underweight, feed them more.

Maintaining your dog's ideal weight is essential for their overall health and longevity. Adjusting food portions based on their body condition can help achieve a healthy balance.
Whether your dog needs to lose or gain weight, gradual adjustments and regular monitoring will ensure they reach and maintain their ideal body condition safely.
Portion sizes vary by several factors like age, breed, activity level, and health conditions.
Use your dog’s ideal weight to determine the correct amount of food, especially if they are overweight or underweight.
Overfeeding can cause obesity, while underfeeding may lead to malnutrition and low energy.
Wet food requires larger portions than dry food due to its higher moisture content.
For dogs with a body weight over 100 pounds, add extra food based on feeding guidelines—typically ⅓ cup per 10 pounds of body weight.
Check dog food labels to calculate daily caloric intake and maintain an ideal body condition.
Consult your vet for guidance, especially for puppies, senior dogs, or dogs with health concerns.
