Highly active breeds and large breed puppies often require more than 7% of their actual weight to maintain healthy body weight. Puppies require more food now than what will be required as a mature adult.
Signs your puppy may need more food are: inhaling or gulping food, begging or constantly asking for treats. If you can see your puppies ribs you should increase food portions.
Signs your puppy is being overfed or may require less food are: noticeable weight gain, (no longer see or feel ribs) leaving food behind or becoming fussy about which foods to eat.
