A 4-month-old, male, Great Dane puppy
Puppy
Growing puppies have higher energy demands than adult dogs. Puppies up to 4 months of age require around twice the amount of energy per unit of body weight as an adult dog of the same breed. As puppies grow, their energy demands begin to decrease. With large and giant breeds (expected adult weight of >45 kg [100 lbs.] assuming the dog has an ideal body condition score) who achieve their adult weight much later (up to 24 months of age), the objective is to feed to ensure a relatively slow and steady rate of growth. Rapid growth rates can stress developing bones and joints resulting in skeletal malformations.
There is wide variation in caloric requirements among dogs. Pets should be fed as individuals to maintain normal growth and a lean, healthy body condition. Plump, heavy puppies are not healthy puppies. The puppy’s body condition (using the Purina Body Condition System) and weight should be continually monitored at home and at regular veterinary appointments.
"Large and giant breed puppies such as [dog's name] need a complete and balanced puppy food until they reach full skeletal maturity, which could take up to 24 months of age. Since puppies, like adult dogs, are individuals, it is important to monitor body condition and adjust the amount being fed accordingly. Feeding measured or weighed meals to your puppy, rather than free-choice feeding, is preferred for slow, healthy growth to reduce the risk of skeletal problems."
