Zeus is a puppy, and he's going to continue to grow during the first year of his life. The good news is that his growth will slow down. Fully grown, Zeus can weight up to 66 pounds, and at around five months of age, he should be getting close to 3/4s of his full grown weight. The only thing you can do is keep feeding him puppy food according to the package instructions, and make sure he exercises for 25 minutes a day twice a day :-)
