Hi Tyler-
It sounds like you have a large breed puppy. If so, large breed puppies have unique dietary needs and can not be fed a regular puppy food. You also need to be careful when feeding a food labeled for “all life stages” unless you are certain is it LBP appropriate. For this reason I tend to gravitate to companies that are known for producing reliably correct large breed puppy foods. My favorite one being Purina Pro Plan. Purina has spent millions of dollars on food trials and research on large breed puppy nutrition and growth. The price point may also be better for you and it is a widely available food. One other thing to note is that Pro Plan in general is highly disgestable, which will be great for his stomach given that he came from a shelter situation. Shelters are horrible places for dogs/puppies to be and it is very stressful, so GI upset is not uncommon in newly adopted dogs/puppies.
