There are a lot to choose from so you might have to try something that looks good and see how the puppy does on it. I used Innova puppy food and my bully did well on it while others have used Fromm with a lot of luck as well. You might want to start there and also look at our dog food ratings page for more information!
Remember, there isn't one food that's great for all bulldogs - it is some trial and error!
