Any food that is 4 stars and above will be great for your pup. Transition slowly. Blue Buffalo recently had a recall so you may want to choose a different brand. AvoDerm and By Nature are also sold at Petsmart.
Once your bully gets older (6 months+) you may want to switch to one of our recommended foods like Fromm, Nature's Logic, or Nature's Variety. You can order it online for the same price as shopping at Petsmart, look for the deals you can get from Petflow.com (use coupon code englishbulldog) and Carolina Pet Pantry carries HALO, Fromm grain free, Acana & Orijen.
Pet insurance is never a bad idea with a bully. @reallyrob @TessaAndSamson I know have it.
