Recommended daily amount: 3 to 4 cups of high-quality dry food a day, divided into two meals.
You'll need to take special care with feeding and exercising a German Shepherd puppy, however. German Shepherds grow very rapidly between the age of four and seven months, making them susceptible to bone disorders. They do well on a high-quality, low-calorie diet (22 to 24 percent protein and 12 to 15 percent fat) that keeps them from growing too fast.
Overfeeding your German Shepherd and letting him pack on the pounds can cause joint problems, as well as other health conditions. Limit treats, keep him active, and serve him regular meals rather than leaving food available at all times.
