When Do American Bulldogs Stop Growing?

If you have an American Bulldog puppy, you may wonder when he will mature. The solution is straightforward! American Bulldogs, like many other large breed canines, take about two years or 24 months to attain full maturity.

This is a longer period than smaller breed dogs, which normally reach adulthood in around a year.

It should be mentioned that some canines develop more quickly than others. It is critical that your dog grows up in a healthy environment and receives the greatest nourishment available. You should take him to the vet regularly.

American Bulldog Growth Chart – What To Expect

American Bulldog Weight  1-2 weeks

Your American Bulldog puppies are underdeveloped at this period and require their mother’s milk for nutrition and warmth. They have touch, smell, and taste, but they can’t hear or sight yet.

Because they gain strength, you may expect them to mostly nap and nursing. They also cannot walk since their muscles are still forming.

Because American Bulldog puppies have a high mortality rate, it is best to separate them immediately after birth to ensure their survival and then reintroduce them to their moms once they can open their eyes. This reduces the likelihood of the mother squeezing them to death irresponsibly.

American Bulldog Weight 3-12 weeks

During this period, your American Bulldog will open his eyes and use his hearing. He will grow strong enough muscles to stand, play with his littermates, run, and bark. He may be a little clumsy at first, but his teeth will grow.

Not only that, but as his eyesight improves, he will progressively gain awareness of his surroundings. He will also regain control of his bowel and bladder functions. As he explores and possibly gets into mischief, his coordination will also develop.

American Bulldog Weight 4-6months

Your American Bulldog puppy is still growing quickly at 6 months old! When you get your puppy at 8 weeks old, he will weigh roughly 15 pounds. He will develop quickly in the first 1/2 year of his life, reaching 50-70 pounds in 6 months.

Females are on the lower end of this scale (and a really small-boned girl may weigh barely 45 pounds), whereas males are on the higher end. If you have a male from a line that breeds tall and powerful canines, your 6-month-old male can weigh up to 75 pounds.

It is critical not to overfeed your dog in order to have him develop quickly. Heredity dictates size, and giving your dog extra calories will simply make him overweight, not taller.

Growing puppies should constantly be kept slender in order to decrease strain on their growing joints and avoid future health problems such as diabetes.

American Bulldog Weight  10-12 months

Your Bully is virtually completely grown at one year of age. You can expect your dog being close to his final weight. He shouldn’t gain over 10 pounds after his first birthday if you don’t overfeed him.

At this age, the average female American Bulldog weighs 65-70 pounds, while the average male weighs 85-90 pounds.

American Bulldog Adult Weight 

If you have a young American bulldog puppy, don’t expect him to stay small for long. Adult males of the breed typically stand between 22 and 27 inches tall at the shoulders. Females are a little shorter, measuring between 20 and 25 inches. Male American bulldogs are often heavier than females. The average mature male weight ranges between 75 and 125 pounds, while females range between 60 and 100 pounds.

What is the Full Grown American Bulldog Weight?

Not every dog is identical, even if they are of the same breed. However, most American Bulldogs will reach a height of 20 to 28 inches and a weight of 60 to 120 pounds.

Many factors, however, must be considered, including food, activity, and heredity. Certain American Bulldogs are simply bred to be smaller or larger. Spaying and neutering may influence adult size as well.

American Bulldog Height Chart

As previously stated, male American Bulldogs can grow to be slightly larger in many areas, including height. However, the average height of an American Bulldog is from 20 and 28 inches.

When compared to Old English or French Bulldogs, the American Bulldog is significantly taller. And, while there is a wide variation of height within the breed, settling somewhere in the mid-20s is a solid bet your bulldog is developing to the right size.

How To Weigh Your American Bulldog Puppy?

To accurately weigh your dog, they should be at their ideal weight. While an obese dog may naturally weigh more, this is not their natural size. When they are breathing heavily, you should be able to see their ribs. The dog’s last two ribs should be visible if it is in a clam state.

Your American Bulldog’s stomach should be tucked up higher than the rib cage. If there are hip points and most of the vertebrae are visible, your dog is underweight. All of our pets were weighed at their ideal weight.

What Is An American Bulldog’s Neck Size?

The best method for determining the neck size is to use a mayo tape or a soft tape measure. Wrap the tape measure firmly around the neck’s widest point. The dog should be relaxed and not panting, else the measurement may be erroneous.

Take in mind that if your American Bulldog is overweight, its head will measure larger, much as a human’s face does when it is overweight. It is usually preferable to keep your dog at an optimal weight for his or her health.

The average size of your American Bulldog’s neck is 45-62cm (18-24″). 

How Big Do American Bulldogs Get?

Adorable American Bulldog puppies will mature to be between 20 and 28 inches tall and weigh between 60 and 120 pounds. Although these are believed to be the breed’s normal sizes, American Bulldogs can be much larger or smaller.

When do American Bulldogs stop Growing?

Many American bulldogs cease growth between the ages of 12 and 14 months; some may not reach full maturity until they reach the age of two. As with humans, dogs are individuals who do not always meet common benchmarks such as weight, height, and growth at the same time.

Factors That Affect American Bulldog Puppy Growth 

Genetics

Your dog’s forebears impact his current physical health since genes are handed down and influence your dog’s ability to grow as well as his susceptibility to certain ailments.

The development of an American Bulldog is heavily influenced by genetic features. These biological determinants control the rate of growth and other important aspects that contribute in their progression.

Diet & Nutrition

Because many low-quality diets do not contain essential nutrients, as responsible dog parents, feed your dogs the most nutritious foods available.

Your American Bulldog’s potential to grow is determined by the food he consumes. If you continually feed him low-quality food that lacks the vitamins and minerals he requires for development, his growth will be hindered. Your dog’s diet impacts both his growth and his general quality of life.

Physical Activity & Health

Because American Bulldogs are excellent hunters, they like physical action. You should ensure that kids get adequate exercise so that they can grow their muscles and bone density. It will aid your puppy’s natural growth and meeting of developmental milestones.

He will also have a better mood and overall well-being if he may engage in regular physical activity. His physique will be fitter, which will help him stay healthy.

A range of fitness activities are enjoyable for American bulldogs. You can play fetch with him, or you and he can go running or on a walk. He will most likely like these activities with you, so make enough time for them.

Common Questions about American Bulldog

At What Age Is An American Bulldog Fully Grown?

This breed matures around the age of 18 months. There will be no modifications in your dog’s height after that. If you continue to exercise your dog regularly, he will gain weight. When your dog is completely grown is also determined by his spay/neuter status.

When a dog is spayed or neutered, the hormone production is disrupted. Male and female sexual hormones inform the body when it is time to cease growing. Dogs who are spayed or neutered at a young age grow taller and longer than their intact littermates.

Males who are neutered early in life, in particular, do not develop a deep and wide chest and always appear more “lanky” than an intact dog. In females, the disparity is less evident.

Main Types and Breeds Of American Bulldogs

John D. Johnson and Allen Scott, two dog breeders, discovered the two breeds of American Bulldogs that exist today. These are the Johnson and Scott American Bulldogs.

Johnson American Bulldogs – These are the largest of the two varieties and are referred to as the “bully” or “classic” American Bulldog. They have a strong resemblance to English Bulldog puppies because of their crossbreeding with this breed.

They are often more muscular in build than the other two categories. John D Johnson designed this kind after conducting research on the English Bulldog breed’s progenitors and the offspring of American Bulldogs.

Scott American Bulldogs — Developed by Allen Scott, this breed is often known as the “performance” or “standard” American Bulldog because of their smaller size but more agility than Johnson American Bulldogs.

They are occasionally confused with the American Pitbull Terrier because of their morphological characteristics.

How Long Are American Bulldogs Pregnant?

The American bulldog’s gestation time is roughly 58 to 68 days, which is consistent with other bulldog breeds. American Bulldogs have an average delivery time of 63 days. The time required for delivery varies according to the mother’s health, age, and breed type.

The duration of your dog’s pregnancy also depends on the litter size. Your veterinarian can perform an X-ray to determine the number of puppies within, so you can plan accordingly.

Many people believe bulldogs are incapable of giving birth normally and always require a c-section. However, this is not true. This is not always the case with C-sections.

How Many Puppies Do American Bulldogs Have?

Bulldog litters have a more predictable range of puppies. Most Bulldog litters will have three or four puppies. Many Bulldog puppies will require veterinarian intervention or a C-section, as they are frequently too huge to fit through the birth canal.

How To Help Your American Bulldog Lose Weight If He Is Overweight 

Maintain Your Dog’s Activity

As with humans, exercise is critical for your overweight dog’s health. Increased movement helps your dog burn off excess energy (and calories consumed). Avoid panic! Exercising your pet does not have to include marathons or lengthy hikes. Regular walks and the opportunity to run and play safely off-leash. Even establishing a stimulating indoor environment that encourages your dog to exercise regularly will assist. Remember different breeds require varying levels of exercise, so visit your veterinarian, breeder, or your dog’s breed standard for recommendations on the amount of activity.

Distinguish Begging from Hunger

Dog’s Activity

Begging is not necessarily motivated by a desire for more food; it is also used to gain attention. (And, by rewarding the behavior, you reinforce and encourage it to continue.) If your dog begs, do not automatically think he is hungry. Trust your instincts and keep track of the date and hour of your last meal. If your dog is prone to begging and you are prone to succumb to those puppy dog eyes, choose a high-protein meal with a fiber blend to help control your dog’s hunger and voluntary food consumption. This manner, you may feed your dog with the assurance that he will feel fuller and content for a longer period of time.

Restriction on treats and table scraps

Even when our dogs are not begging, many of us provide an excessive amount of treats and table scraps. Dogs are not required to share our food! Consider snacks and scraps for your pet in the same way that you would candies for youngsters to assist you keep them in check. If you’re going to use snacks for training, choose low-calorie, low-fat ones and keep the portions small.

As an alternative, keep in mind that clickers are excellent for reinforcement… and they have no calories! After all, a few extra pounds can make a significant impact in the lives of dogs, which are significantly smaller than humans. (Even the colossal breeds!) Therefore, focus on a balanced diet and resist the temptation to “reward” them with extra.

Individualize Your Dog’s Diet

Not all weight-loss foods are made equal, which is why it’s critical to fit your dog’s dietary plan to their unique needs. Choose a brand that caters to your dog’s unique needs, whether they be weight control, dietary sensitivities, or illnesses.
