When you bring home an XL or XXL American Bully, you aren’t just getting a pet; you are raising a powerhouse. Understanding the growth trajectory of these massive dogs is essential for their long-term health. At Topdog Bullies, we have spent over 16 years perfecting the art of producing 100lb+ companions with stable frames and athletic builds.
Because these dogs grow so rapidly, owners must monitor their development closely. This guide outlines the typical growth stages for an XL American Bully and provides tips on how to manage their size responsibly. Whether you are looking for a blue tri xl bully or a chocolate merle, the growth foundations remain the same.
XL Bully Weight Chart: Milestones from 8 Weeks to Maturity
The most dramatic changes in your puppy happen between birth and six months. During this window, your XL Bully will seem to grow daily. Using a consistent weight chart helps you ensure they are on the right track without becoming overweight, which can stress young joints.
Birth to 8 Weeks: The Foundation
During this stage, the focus is on weaning and social development. Most XL Bully puppies leave our facility weighing between 15 and 25 pounds, depending on the specific bloodline, such as our Show Stoppin Ace descendants.
2 to 4 Months: The Growth Spurt
This is the stage where the “XL” starts to show. You will notice a significant increase in height and bone density. It is common for puppies to gain 2–4 pounds per week during this period. Keep your puppy on a high-quality large-breed formula to support this pace.
4 to 6 Months: Height vs. Weight
By six months, your XL Bully may reach 60% to 70% of its adult height. However, they will still look “lanky.” Do not be tempted to overfeed them to make them “thick” yet. Their frames need time to catch up to their height.
| Age | XL Bully Weight | XXL Bully Weight |
|---|---|---|
| 8 Weeks | 15–18 lbs | 18–25 lbs |
| 4 Months | 45–55 lbs | 55–65 lbs |
| 6 Months | 65–80 lbs | 80–95 lbs |
| 12 Months | 85–110 lbs | 110–130 lbs |
| 24 Months | 100–120 lbs | 130–150+ lbs |
Feeding for Size | Nutrition Plans for XXL American Bullies
A massive frame requires massive fuel. However, quality matters more than quantity. We recommend a diet rich in animal proteins and healthy fats to support the energy needs of a growing XXL Bully.
Many of our owners find success with a raw-fed diet or a high-end kibble supplemented with fresh proteins like beef or chicken. Avoid “filler” foods containing excessive corn or soy. These can cause bloating and digestive upset without providing the caloric density needed for a 100lb+ dog. Adding supplements like coconut oil can also benefit their coat and skin health.
Safe Exercise | Protecting Large Breed Joints During Development
Because XL Bullies carry so much weight, their joints are under constant pressure. While you want your dog to be muscular, you must protect their growth plates during the first 18 months of life.
Exercise Guidelines:
Avoid High Impact: Do not encourage your puppy to jump off high surfaces or perform repetitive “impact” tricks.
Controlled Play: Allow them to play at their own pace. On our 20-acre farm, our dogs get plenty of supervised free-play time to build natural muscle.
Soft Surfaces: When possible, exercise your Bully on grass or dirt rather than concrete to reduce shock on their paws and elbows.
The Science of the Build | How Bloodlines Impact Growth
Consistency in growth comes from consistency in breeding. At Topdog Bullies, we utilize world-famous lines like Gotty, Greyline, RCP, and Bossy. These lines are known for producing predictable “heavy-boned” results with the massive heads and wide chests the breed is famous for.
When you buy a puppy from a proven line, such as a direct Ace son or an El Cucuy production, you aren’t guessing about the final size. You are investing in a genetic blueprint that has been refined over 16 years to ensure the dog grows into a balanced, impressive adult.
XL vs. XXL Bullies | Understanding the Size Differences
It is important to know which class your dog falls into. While “XXL” is often a descriptive term for extreme size, the ABKC standards provide clear guidelines for the XL class.
XL American Bullies: Males stand between 20 and 23 inches at the withers; females are 19 to 22 inches.
XXL Bullies: These dogs often exceed the standard height and weight, frequently pushing over 130 pounds while maintaining the Bully “type”: thick frames, broad chests, and massive bone.
At Topdog Bullies, we focus on producing both. Whether you want a standard-sized companion or a “Magical God Loki” style powerhouse, structure remains our top priority.
