- Unofficial Status: “XXL” is not a separate registry class; it typically refers to the largest XL Bullies that exceed standard height and weight limits.
- Massive Size: Expect heights over 23 inches and weights ranging from 110 lbs to over 170 lbs.
- High Cost: These are among the most expensive dogs to buy and own, with puppy prices often hitting $4,000–$10,000+ (£3,000–£8,000+).
- Health Focus: Due to their extreme mass, joint health (hips and elbows) is the single biggest concern for owners.
Physical Characteristics: How Big Do They Get?
When we talk about size, the XXL is in a league of its own. While a Standard American Bully might weigh 70 lbs, an XXL can easily double that.
| Feature | Typical Specification |
|---|---|
| Height | 23 inches and up (Males), 22 inches and up (Females) |
| Weight | 110 lbs to 170 lbs+ |
| Head Size | 24 to 28+ inches circumference |
| Lifespan | 8 to 11 years |
The goal for a high-quality XXL is to maintain the “Bully” look—blocky head, wide chest, thick bone—without looking like a tall, lanky Great Dane. You want thickness and height.
[pro_tip]
Always ask to see the parents (dam and sire) before buying an XXL puppy. Puppies grow into their genetics. If the parents have weak pasterns (wrists that bend down) or swaybacks, the puppy likely will too, especially once they pack on 100+ lbs of weight.

Temperament: Are They Dangerous Giants?
Despite their intimidating size, the temperament of a well-bred XXL American Bully should be identical to a Pocket or Standard: gentle, affectionate, and stable.
The American Bully was created specifically to be a companion dog. Breeders removed the dog-aggression found in the Pit Bull Terrier and the drive of the AmStaff to create a family-friendly animal. An XXL should be a “gentle giant.” They are known for being exceptionally tolerant with children and bonded to their families.
However, size matters when it comes to training. A 150 lb dog that jumps up to say hello can accidentally knock over a grandmother or a child. They require strict boundary training simply because of their physics.

Health Realities for the Biggest Bullies
This is the most critical section of this guide. You cannot own an XXL Bully without being proactive about health. When you breed dogs for extreme size, you invite structural issues.
1. Joint Issues (Hip & Elbow Dysplasia)
Gravity is the enemy of the XXL. Carrying 140 lbs on a frame meant for a medium-sized dog puts immense pressure on joints. Hip dysplasia is rampant in the XXL class. This is where the ball and socket of the hip joint don’t fit together correctly, causing grinding, pain, and arthritis.
We have a detailed breakdown of American Bully hip dysplasia that explains the signs to look for, but as a buyer, you must demand health testing. Ask for OFA (US) or BVA (UK) scores on the parents. If a breeder says, “My dogs are vet checked” but cannot produce X-rays, walk away.
2. Heart Conditions
Larger dogs work their hearts harder. Subaortic Stenosis and other cardiac issues can shorten an XXL’s life.
3. ACL Tears
Due to their heavy fronts and explosive muscle, XXLs are prone to tearing their Cruciate Ligaments (ACL/CCL) if they play too rough or jump out of tall vehicles.
4. Overheating
These dogs carry a lot of muscle and often have slightly shorter muzzles than other mastiff breeds. They do not tolerate heat well. An XXL can overheat in minutes during a humid summer day.
How Much Does an XXL American Bully Cost?
The XXL is generally the most expensive class of American Bully alongside the “Micro” Exotic. You are paying for the mass, the “wow” factor, and the feed bill the breeder paid to get them there.
Puppy Prices
Prices depend heavily on bloodlines, structure, and the reputation of the kennel.
| Quality Tier | Typical US Price ($) | Typical UK Price (£) |
|---|---|---|
| Pet Home (No papers) | $1,500 – $2,500 | £1,000 – £2,000 |
| Standard Breeder | $3,000 – $5,000 | £2,500 – £4,500 |
| Top Bloodline / Pick of Litter | $6,000 – $10,000+ | £5,000 – £8,000+ |
| “Celebrity” Stud Offspring | $15,000+ | £12,000+ |
The “Hidden” Costs
The purchase price is just the entry fee. The ongoing costs for an XXL are significantly higher than for a Pocket or Classic.
- Food: An XXL can eat 4–6 cups of high-quality kibble a day, plus raw supplements. Expect to spend $150–$250 (£100–£200) per month on food alone.
- Supplements: You will need joint supplements (Glucosamine/Chondroitin) from day one.
- Vet Bills: Medications are dosed by weight. Heartworm prevention and flea meds for a 140 lb dog cost twice as much as for a 60 lb dog.

Famous XXL Bloodlines
Bloodlines are brands in the dog world. In the XXL lane, a few names dominate. Knowing these helps you understand what you are buying.
DDK9 (The Hulk)
Perhaps the most famous American Bully in history, “Hulk” from Dark Dynasty K9s pushed the XXL category into the mainstream. Weighing over 170 lbs, Hulk represents the extreme end of the spectrum. Dogs with DDK9 in their pedigree are bred for massive size and protection capability, which differs slightly from the standard “companion only” ABKC temperament.
Gottiline
While Gottiline founded the modern Bully look, specific offshoots of this line were bred up in size to create the XXL foundation. They are known for wide chests and heavy bone. You can read more about the history of the Gottiline American Bully bloodline to see how it influenced the breed’s mass.
Iron Cross & BGK
These kennels were instrumental in establishing the “tall and thick” look that defines the XXL today.
Feeding a Giant: Nutrition Rules
You cannot just feed an XXL puppy generic supermarket kibble and expect them to grow correctly. However, a common mistake is overfeeding calcium to try and make the bones grow bigger.
Do not do this.
Overfeeding calcium or calories to a giant breed puppy causes them to grow too fast. Their weight increases faster than their joints can calcify, leading to permanent skeletal damage (Knuckling Over or Panosteitis).
- Protein: Look for 24-30% protein.
- Fat: Moderate fat levels to prevent obesity.
- Feeding Schedule: Feed puppies 3-4 times a day, transitioning to 2 times a day as adults.
[pro_tip]
Invest in a raised bowl feeder. XXL Bullies are tall, and eating from the floor can cause strain on their neck and shoulders. It also helps with digestion in larger breeds.

Legal Issues and Insurance
Before you bring an XXL home, you have to do your homework regarding the law.
United States
While there is no federal ban, the American Bully is frequently targeted by Breed Specific Legislation (BSL).
- Housing: Many rentals have weight limits (often 50 lbs) which instantly disqualifies an XXL. Even without weight limits, they are often banned under “Pit Bull type” clauses.
- Insurance: Major carriers like State Farm and Allstate have historically had restrictions on Bully breeds. You must verify your homeowner’s liability coverage before buying.
- HOA: Check your Homeowners Association bylaws.
United Kingdom (Crucial Update)
As of 2024, the XL Bully ban in England and Wales affects the XXL. Because the ban is based on physical measurements (height and head shape), all XXL American Bullies fall under the definition of an XL Bully.
- They must be registered on the Index of Exempted Dogs.
- They must be muzzled and on a lead in public at all times.
- They must be neutered.
- Buying, selling, or breeding them is currently illegal.
If you are in the UK, you effectively cannot buy a new XXL puppy legally at this moment. You can only own one if you already had it registered prior to the deadline.
Finding a Reputable Breeder vs. Scams
The high price tag of XXL Bullies attracts scammers. The US market is flooded with backyard breeders selling “XXL” puppies that are actually just mixed-breed dogs or unhealthy giants.
Red Flags
- Merle Pricing: Charging $10,000 just because a dog is Merle. While beautiful, Merle is a pattern, not a structure. Read our article on the Merle American Bully to understand the genetics and risks involved.
- Craigslist/Facebook Marketplace: Reputable breeders do not sell puppies next to used sofas.
- “Ready to Go” at 6 Weeks: Puppies need to stay with their mother until at least 8 weeks.
- No Health Guarantees: If they won’t guarantee the hips for 1-2 years, do not buy the dog.
Green Flags
- ABKC/UKC Registration Papers in hand.
- Health Testing (OFA/PennHIP) results visible.
- Clean Kennels: They allow you to video chat or visit to see the conditions.
We have compiled a complete checklist of documents, health questions, and scam warnings in our American Bully Buyer’s Guide. It covers the specific questions you need to ask an XXL breeder to ensure you aren’t buying a puppy with dysplastic hips. You can get the guide at BullyOwners.com for just $17 / £13.99. It could save you thousands in vet bills later.
Is the XXL Right for You?
Owning an XXL is a lifestyle choice. They take up the entire back seat of your car. They clear coffee tables with their tails. They cost as much to feed as a teenager.
Pros
- Deterrent: No one is breaking into a house with a 150 lb dog guarding it, even if the dog is actually a big softie.
- Temperament: Generally calmer and lower energy than the frantic energy of some smaller terriers.
- Companionship: They are incredibly affectionate and bond deeply with their owners.
Cons
- Cost: Expensive to buy, expensive to feed, expensive to vet.
- Lifespan: Heartbreak comes sooner with giant breeds.
- Stigma: People will cross the street to avoid you. You must be an ambassador for the breed.
- Physical Strength: You need to be physically capable of holding back 150 lbs of muscle if they decide to chase a squirrel.
Comparison to the XL Class
Many buyers debate between the XL and the XXL. The main difference is agility. A standard XL American Bully is usually more functional. They can run longer, handle heat better, and have fewer joint issues because they are carrying less weight.
If you want a hiking partner or a dog to do agility work with, go for a standard XL. If you want the maximum size and a slower-paced companion for short walks and hanging out, the XXL is the choice.
Conclusion
The XXL American Bully is an impressive feat of canine breeding. They are head-turners, loyal family guardians, and gentle giants. But they are not for everyone. They require a significant financial commitment and a dedication to managing the health issues that come with their size.
If you are ready for the drool, the food bills, and the giant cuddles, there is no other dog quite like them.
