Hi, you got really good advice from everyone above. I have two 16 month old siblings, Bulldozer and Blossom. They were on puppy food until they were 7 months old, and I fed them 1 cup 3 times a day. Then I switched to two 1 cup feedings a day, one in the morning, and one in the evening. They get plain yogurt on their kibble in the morning, and I give them treats during the day like cut up apples, or they share a banana, or strawberries, cheese strings, or green beans. My two both weigh 45 lbs, but my vet wants me to keep them at 40 lbs, so suggested I cut back their food to 3/4 of a cup twice a day, I don't think they are overweight, but she says it's hard on their joints to be overweight. My two get two long walks a ay, once in the morning, and once in the evening, we let them run free down at the trail and river behind my house in the morning when it's cooler outside. There isn't really any set rules on the feeding schedule or amounts as every bully is different, mine are smaller, so twice a day feedings are fine for them, also you can gage it on the poops, if they are pooping many times a day, or if they are soft or mushy, then it may be too much food. My guys poop two or three times a day, and they are soft but firm. If your guy isn't overweight, as this is not good for their back or joints, and his poops are good, then you can give a little more food. Your baby is super cute.
