At this age, I would switch to adult food, a grain free food with a red meat base from roast's not meal. For instance, beef, bison or venison. Fromm Beef Fritata, or Taste of the Wild Prairie check the food ratings here on EBN and then Pet Flow will have all those foods and the ingredients. I started all my bully's on adult food at 5 to 6 months old. three times a day, at a year old two times a day. If your pup is undersized, give a little more.
