English bulldogs are medium-sized pooches who will grow to between 40 and 50 pounds in size when they are adults. This growing process may take a bit longer than in a smaller breed, around 18 months instead of 12.
When English Bulldogs are Fully Grown
English bulldogs, simply classified as bulldogs by the American Kennel Club, are considered fully grown when males reach about 50 pounds and 16 inches in height and females reach 40 pounds and 14 inches in height. According to the Royal Canin website, English bulldogs are considered adults at 12 months of age. While a bulldog may be classified as an adult at a year old, all of his growing may not be done until he reaches 18 months of age, states the Bulldog Rescue & Rehoming website. Most of an English bulldog pup's bones fuse between 9 months and 1 year of age, but the bones in his legs and elbows may be developing until he reaches around 1 1/2 years old.
Food for the Growing English Bulldog
English bulldogs are prone to developing bone and joint issues that can be brought about by obesity and excessive exercise while they're still developing. Speak with your vet about feeding him puppy food beyond 5 months of age. Puppy food is higher in protein, calories and calcium than adult dog food and may encourage rapid growth of your bulldog's bones, leading to joint issues later in life.
