How Much to Feed American Bully Chart: Puppy to Adult Guide

Most dog food bags are lying to you. If you follow the manufacturer’s recommended serving size on the back of the bag, you will likely end up with an overweight dog and a lighter wallet. Dog food companies want you to finish the bag faster so you buy another one.

When it comes to the American Bully, following generic advice is dangerous. This breed ranges from the compact Pocket class (under 17 inches) to the massive XXL (over 23 inches and 140+ lbs). A single generic feeding guideline cannot cover a 50lb dog and a 150lb dog simultaneously.

Getting the nutrition right is the difference between a muscular, athletic dog and a sluggish one with joint pain. This guide breaks down exactly how much to feed american bully chart style, separating the needs of different classes and ages so you can build a healthy dog, not just a fat one.

The Ultimate How Much to Feed American Bully Chart

The following table provides a baseline starting point. These numbers represent total daily intake, which should be divided into multiple meals.

Note: “Cups” refers to a standard 8oz measuring cup using high-quality kibble (approx. 350-400 kcal per cup). If you use a calorie-dense performance kibble (500+ kcal/cup), you must reduce these amounts by 20-30%.

Understanding the Variables

The chart above is a baseline. You cannot simply pour the food and walk away. Several factors dictate whether you need to scoop more or less.

The Class Difference

The American Bully comes in distinct classes. A Pocket American Bully has a much lower caloric ceiling than an XL. Pockets are prone to becoming “sausages” if overfed because their frames are shorter. They pack weight on quickly, which puts immense pressure on their elbows.

Conversely, an XL or XXL has a massive skeletal structure to support. They need the calories to grow bone and muscle, but the type of calorie matters. You want slow, steady growth for XLs to prevent structural weakness.

Metabolism and Activity

Is your Bully a couch potato, or are they working? A dog that sleeps 16 hours a day requires about 20% less food than the chart suggests. A dog that is exercised heavily, does weight pull, or runs daily will need 20-30% more.

Never feed your American Bully immediately before or after heavy exercise. This breed is susceptible to bloat (Gastric Dilatation-Volvulus), a life-threatening condition where the stomach twists. Wait at least 45 minutes after exercise to feed.

Puppy Feeding Schedule (8 Weeks to 12 Months)

The first year is where you build the foundation. Mistakes here stick with the dog for life.

8 to 12 Weeks: The Transition

When you first bring your puppy home, they are in a rapid growth phase. Their stomachs are small, so they cannot handle large volumes of food. You must split their daily ration into 3 or 4 meals.

If you feed them too much at once, you’ll see loose stool immediately. This is a sign their digestive system couldn’t process the load. Keep the meals small and frequent to keep their blood sugar stable.

3 to 6 Months: The “Ugly Phase”

During this window, your Bully might look lanky. They grow upwards before they grow outwards. New owners often panic here and try to “fatten up” the dog because they want that wide, bulky look immediately.

Do not do this.

Let them be lanky. If you force-feed a puppy during this height-growth phase, you are adding weight to soft, developing joints. This is a primary cause of environmental [hip dysplasia in American Bullies](https://bullyowners.com/american-bully-hip-dysplasia/). Keep them lean. You should be able to feel their ribs easily but not see them clearly.

6 to 12 Months: Filling Out

At this stage, the height growth slows down, and the chest begins to drop and widen. You can switch to 2 meals a day (morning and night). This fits better with most work schedules and helps regulate their bowel movements.

Raw vs. Kibble: Adjusting the Math

The how much to feed american bully chart changes completely if you switch from kibble to a raw diet. Kibble is dehydrated and calorie-dense. Raw food is 70% moisture.

Calculating Raw Feeding Amounts

If you opt for a raw diet, you don’t measure in cups; you measure in weight.

• Puppies: Feed 5% to 8% of their current body weight daily.
• Adults: Feed 2% to 3% of their ideal body weight daily.

For example, a 100lb (45kg) male XL Bully on a raw diet would need roughly 2lbs to 3lbs (0.9kg – 1.3kg) of food per day.

There are massive benefits to raw feeding, including better skin health and smaller stools, but it requires freezer space and preparation. If you are interested in making the switch, read our guide on the [pros and cons of a raw diet for American Bullies](https://bullyowners.com/raw-diet-for-american-bully-pros-cons) to see if it fits your lifestyle and budget.

The Cost of Feeding

Before you bring a Bully home, you need to budget for their stomach. These dogs are not cheap to feed.

Monthly Food Costs (Average):

• UK: £80 – £200
• US: $100 – $250

This variance depends on whether you buy premium kibble or bulk raw ingredients. An XXL Bully eating 8 cups of high-end kibble a day acts like a vacuum cleaner for your wallet.

If you are currently looking for a puppy, understanding these ongoing costs is just as important as the initial purchase price. We break down the full cost of ownership—from insurance to vet bills—in our American Bully Buyer’s Guide. It helps you verify you aren’t buying a money pit.

The Danger of Power Feeding

“Power feeding” is a toxic trend in the Bully community. This involves feeding puppies high-calorie weight gainers, puppy milk replacers, and excessive kibble to make them look “massive” at 6 months old.

This destroys dogs.

An American Bully puppy has growth plates that do not close until 18-24 months. If you overload a 6-month-old puppy with 20 extra pounds of fat, that weight pushes down on soft cartilage. The result is weak pasterns (flat feet), cow hocks (rear legs turning in), and early-onset arthritis.

A healthy Bully puppy should have an abdominal tuck. They should have a waist. The “mass” comes from genetics and maturity, typically hitting fully between 2 and 3 years of age. You cannot feed your way to better genetics.

Nutritional Requirements: What to Look For

Whether you choose kibble or raw, the macronutrient profile matters more than the brand name.

Protein vs. Fat Ratio

For an active American Bully, look for a ratio near 30% Protein / 20% Fat.

• Protein: builds the muscle mass the breed is famous for.
• Fat: provides the energy fuel.

If the protein is too low (under 24%), your dog will struggle to maintain muscle tone. If the fat is too high and the dog isn’t working, they will get obese.

Ingredients to Avoid

American Bullies are notorious for sensitive skin. Many suffer from environmental and food allergies that manifest as itchy paws, red bellies, and bumps along the back.

Avoid foods where the first ingredients are:

• Corn
• Wheat
• Soy
• Unidentified “Meat Meal”

These are cheap fillers. If your dog is constantly itching or biting their paws, check the food label first. Diet is the number one trigger for [skin problems and allergies](https://bullyowners.com/american-bully-skin-problems-allergies/) in this breed.

Supplements: Necessary or Hype?

You don’t need a shelf full of powder tubs to have a healthy dog. However, two supplements are actually worth the money for this specific breed.

1. Joint Support (Glucosamine, Chondroitin, MSM) Because of their heavy bone structure, Bullies put more torque on their joints than lighter breeds. Starting a joint supplement early (around 1 year old) acts as insurance for their later years.

2. Omega 3 (Salmon Oil) This helps with the skin issues mentioned above. It reduces inflammation and keeps the coat shiny.

Be careful with calcium supplements. Never give extra calcium to a puppy on a balanced commercial diet. Excess calcium can cause bone deformities and interfere with proper skeletal growth.

How to Tell if You Are Feeding the Wrong Amount

The chart is just a guide. Your dog’s body is the truth.

Signs of Underfeeding:

• Ribs and spine are clearly visible from a distance.
• Hip bones protrude sharply.
• Low energy or lethargy.
• Dull, dry coat.

Signs of Overfeeding:

• No visible waist when looking from above.
• You cannot feel the ribs even when pressing firmly.
• Fat pads forming over the hips or base of the tail.
• Labored breathing after short walks.

If you have a puppy that is biting excessively or acting out around food bowls, they might be genuinely hungry, or they might just be testing boundaries. It is important to distinguish between hunger and behavioral phases. Check our guide on [fixing puppy biting and mouthing](https://bullyowners.com/american-bully-puppy-biting-mouthing-fix) to ensure you aren’t confusing a training issue with a hunger issue.

Final Thoughts on Feeding

Feeding your American Bully isn’t about hitting a specific number on a scale. It is about fueling the dog in front of you.

If your dog looks thin, add a half-cup. If they look soft, take a half-cup away. Monitor their stool—firm and small means good absorption; loose and huge means you are overfeeding or the food quality is poor.

Keep them lean while they grow. Protect their joints. The mass will come with time.

An 8-week-old American Bully should eat between 1.5 to 3 cups of high-quality puppy food per day, depending on their class (Pocket vs. XL). This total amount must be divided into 3 or 4 small meals to prevent digestive upset.

Switch to adult food around 12 months of age. For XL and XXL Bullies, some owners wait until 18 months to ensure they get the growth-specific nutrients longer, but monitor their weight to ensure the higher calorie puppy food isn’t making them obese.

Raw food often results in better skin health, smaller stools, and cleaner teeth. However, high-quality grain-free kibble is perfectly acceptable. The “best” food is the one that provides complete nutrition that your specific dog digests well and fits your monthly budget.

Bullies are food-motivated dogs. They will often act hungry even when full. If their body condition is good (waist visible, ribs felt but not seen), ignore the begging. Overfeeding leads to obesity and joint failure.
