Height is mostly set by about 12 months, but chest and muscle keep developing until 18 to 24 months. Large dogs take longer to mature than small ones, so keep feeding a growth-appropriate diet and have your vet confirm when to switch to adult food. Growth Stages Birth to 12 Weeks Newborn puppies are blind and deaf for the first 1 to 2 weeks and depend on their mother. Most puppies go to their new homes at about 8 weeks. At that age they often weigh around 15 pounds, and early socialization, vaccinations and gentle handling are the priority. 4 to 6 Months Growth is fast. By 6 months many puppies weigh around 45 to 75 pounds, with females often toward the lower end and large males toward the upper end. Rapid growth makes weight control important. Extra weight stresses developing joints and raises the risk of joint problems later. 10 to 12 Months Your dog now looks almost like an adult. Many females are around 65 to 70 pounds and many males around 85 to 90 pounds, though bloodlines vary. A few more pounds may be added over the next year as muscle fills out. Adult American Bulldog Size Males Females Height at shoulder About 22 to 27 in (56 to 69 cm) About 20 to 25 in (51 to 64 cm) Weight About 75 to 125 lb (34 to 57 kg) About 60 to 100 lb (27 to 45 kg) Standard and Scott or Johnson bloodlines differ in build and size. What Affects Growth Genetics: the parents’ size and health are the best clue. Nutrition: complete and balanced food for the life stage. Large-breed puppy food has controlled calcium and calories. Exercise: daily walks and play build muscle. Avoid long runs, forced jumping and rough stairs when young. Health: parasites, illness or hormone problems can affect growth. Food for Growing American Bulldogs Pick a large-breed puppy formula until your vet recommends adult food. High-protein bodybuilding formulas are not necessary, and overfeeding can speed growth too much. Is My American Bulldog a Healthy Weight? You can feel the ribs without pressing hard.
