American Bully Puppy Feeding Schedule: Month-by-Month Growth Guide

Nothing stresses a new owner out like staring at a dog bowl and wondering if it is enough. You see massive American Bullies on Instagram with thick necks and huge chests, and then you look at your puppy and worry they are too small. You might feel tempted to fill that bowl to the brim to help them bulk up. This is dangerous. Feeding your dog too much to force growth is the fastest way to ruin their joints before they even turn one. But underfeeding them means they miss out on the nutrients they need to build that signature muscle. You need a plan that balances growth with long-term health.

This guide breaks down the exact american bully puppy feeding schedule you need to follow from the day you bring them home until they are fully grown.

Use this table as your quick reference guide. It changes based on the age of your dog and their specific developmental stage.

8 to 12 Weeks: The Foundation Phase

When you first bring your American Bully home, their stomach is tiny. They cannot handle large amounts of food at once. If you feed them too much in one sitting, they will vomit or get diarrhea. The goal right now is consistency.

You must feed them four times a day. Space these meals out evenly. For example, you could feed at 7:00 AM, 11:00 AM, 3:00 PM, and 7:00 PM. This keeps their energy levels stable and stops their blood sugar from dropping too low.

Stick to the food the breeder was using for at least the first two weeks. Moving to a new home is stressful for a puppy. Changing their food at the same time adds stress to their digestive system. If you want to switch brands, do it slowly after they have settled in.

Mix a small amount of warm water or goat’s milk into their kibble during this stage. It makes the food easier to digest and helps keep them hydrated.

During this phase, you are setting the stage for their future eating habits. Do not leave food out all day. Put the bowl down for 15 minutes. If they do not eat it, pick it up. This teaches them to eat when food is available and helps with potty training.

If you are unsure which brand to switch to later, look for high-protein options specifically designed for medium to large breeds.

3 to 6 Months: The Growth Spurt

At the 12-week mark, your puppy’s stomach has grown. They can handle more food at one time. You can now drop from four meals a day down to three.

This is the “ugly duckling” phase. Your American Bully might look lanky. Their legs might seem too long for their body. This is normal. Do not panic and try to feed them extra to fill them out. They are growing upward right now, not outward.

Protein is critical here. You want a food source that provides at least 30% protein. This supports the muscle development that the breed is known for. However, you must watch the fat content. Too much fat leads to a chubby puppy, not a muscular one. A chubby puppy puts stress on soft growth plates.

Monitor their poop. If it is soft or runny, you might be overfeeding. Firm stool usually means the portion size is correct.

6 to 12 Months: Filling Out

By six months, the rapid upward growth starts to slow down. You can switch to a simple morning and evening feeding schedule (two meals a day).

This is where many owners make mistakes. They see the height growth slowing and think the dog is done growing. They switch to adult food too early or stop measuring portions. Your American Bully is still building bone density and muscle.

Continue using a puppy formula or an “all life stages” formula. Adult food often lacks the calorie density a young Bully needs. However, keep a very close eye on their weight. You should be able to feel their ribs but not see them clearly. If you cannot feel the ribs, cut back the portion size slightly.

This period is also when genetic joint issues often show up. Excess weight exacerbates these problems. If you notice your dog struggling to get up or hopping when they run, consult a vet immediately. Managing their weight through diet is the best way to prevent severe American Bully hip dysplasia.

Raw vs. Kibble: Which is Best?

There is a huge debate in the Bully community about raw feeding versus kibble. Both can work, but they have different pros and cons.

Kibble is convenient and easy to store High-quality kibble is scientifically balanced for nutrients Kibble is generally cheaper than a full raw diet Hard kibble can help scrape plaque off teeth

Kibble often contains fillers like corn or soy High-heat processing kills some natural nutrients in kibble Raw diets require significant freezer space Raw feeding carries a risk of bacterial contamination if handled poorly

If you choose kibble, buy grain-free options if your budget allows. American Bullies are prone to skin allergies, and grains are a common trigger. If you choose raw, do not just throw ground beef in a bowl. You must balance muscle meat, bone, and organs (usually an 80/10/10 ratio). If you get the calcium ratio wrong with a raw diet, you can permanently damage your puppy’s bone structure.

Supplements: Necessary or Hype?

You will see ads for “muscle builder” powders and pills. Most of these are unnecessary if you are feeding a high-quality diet. However, two supplements are actually worth your money for this breed.

1. Joint Support (Glucosamine and Chondroitin) Because American Bullies carry a lot of weight on their frames, their joints take a beating. Starting a joint supplement early (around 6 months) can protect their cartilage. It acts as an insurance policy for their later years.

2. Fish Oil (Omega-3) Bullies often suffer from dry, itchy skin or hives. Salmon oil or other fish oils help keep their coat shiny and their skin healthy. It also helps reduce inflammation in the body. If your dog is constantly scratching, check out our guide on American Bully skin problems and allergies before changing their entire diet.

Feeding by Class: Pocket vs. XL

Not all American Bullies eat the same amount. A Pocket Bully has different caloric needs than an XL.

Pocket and Standard: These dogs are shorter and more compact. They pack weight on easily. You must be strict with portions. A cup of high-calorie food might be too much for a Pocket, leading to obesity quickly.

XL and XXL: These dogs are much larger and have more bone to support. They need more calories, but they also grow faster. Rapid growth is painful. You might need to feed an XL slightly more food, but you should never let them get fat. The heavier an XL American Bully gets during puppyhood, the more strain they put on their developing skeleton.

The Danger of “Power Feeding”

“Power feeding” is the practice of overfeeding a dog or using high-calorie supplements to make them grow huge.

Do not do this.

Genetics determine how big your dog will get. Food only fuels that growth. If you overfeed a dog destined to be 80lbs, you won’t get a 100lb muscle dog. You will get an 80lb dog with 20lbs of fat and destroyed joints.

A lean puppy is a healthy puppy. It is better for them to grow slowly and steadily. They will reach their genetic maximum size eventually. Rushing it only causes long-term health bills.

Common Feeding Mistakes to Avoid

Even experienced owners slip up. Avoid these common traps to keep your puppy healthy.

1. Free Feeding Leaving a full bowl out all day is bad for Bullies. They love food. They will eat out of boredom. This leads to obesity and makes it harder to tell if they are sick (since you won’t notice if they skip a meal).

2. Too Many Treats Training requires treats, but those calories count. If you do a heavy training session, reduce their dinner portion. Use small, low-calorie treats or even pieces of their regular kibble.

3. Switching Food Too Fast If you want to change brands, mix the new food with the old food over 7 days.

• Days 1-2: 25% new, 75% old
• Days 3-4: 50% new, 50% old
• Days 5-6: 75% new, 25% old
• Day 7: 100% new

4. Ignoring the Water Bowl Kibble is dry. Your dog needs plenty of fresh water to digest it. Always keep water available, except perhaps right before bed during potty training.

Wait at least one hour after feeding before you exercise your American Bully. This breed can be prone to bloat, a life-threatening condition where the stomach twists. Resting after meals reduces this risk.

A Note on Hydration

Hydration is just as important as food. American Bullies overheat easily because of their muscle mass and shorter muzzles.

In the summer, you might notice they eat less. This is normal. Digestion creates body heat. If it is hot, they might skip a meal. Ensure they have cool water. If you feed dry kibble, adding water to the bowl helps ensure they get enough fluid intake.

When to Switch to Adult Food

You should generally switch from puppy food to adult food around 12 months of age.

However, for XL Bullies, some vets recommend staying on a large-breed puppy formula until 18 months because they mature slower. If you switch too early, they miss out on the nutrients needed to finish their bone development. If you switch too late, the high calorie count of puppy food will make them overweight.

Watch your dog’s body condition. If they start looking thick around the waist, it is time to switch to adult food or reduce portions.

The Cost of Feeding

Feeding an American Bully properly is not cheap. In the US, a high-quality bag of kibble can cost $60 to $100 a month. In the UK, you are looking at £50 to £90.

Raw feeding is significantly more expensive. You might spend $150 to $250 (£120-£200) a month depending on where you source your meat.

Do not try to save money by buying the cheapest dog food at the grocery store. These cheap foods are full of corn and wheat fillers. Your dog will have to eat twice as much to get the same nutrition, so you don’t actually save money. Plus, the vet bills for skin allergies will cost more than the premium food would have.

Final Thoughts on Routine

Your American Bully thrives on routine. Feed them at the same times every day. Use the same bowl. Put the bowl in the same spot.

This structure makes them feel secure. It also prevents food aggression. If they know food is coming at a specific time, they are less likely to guard their resources.

Remember, the amount on the back of the dog food bag is just a guideline. It is a starting point. Every dog is different. An active dog who runs all day needs more food than a dog who sleeps on the sofa. Watch your dog, not just the measuring cup. Adjust as needed to keep them lean, muscular, and happy.

You can start raw feeding as early as 8 weeks, but most owners wait until 6 months. If you start young, use a pre-made raw grind specifically balanced for puppies to ensure they get enough calcium.

Puppies burn massive amounts of energy growing. However, Bullies are also very food-motivated. If they are maintaining a healthy weight but act hungry, add green beans to their meal to fill them up without adding calories.

Look for a minimum of 30% protein and 18-20% fat for puppies. This ratio supports muscle growth without causing them to gain unhealthy fat.

No. Once they are weaned from their mother, they do not need milk. Cow’s milk gives many dogs diarrhea. If you want to add a liquid topper, use goat’s milk or bone broth instead.
