American Bully Diet
Kibble, raw or home cooked, what a balanced diet actually contains, and the supplements that are worth the money.
A good American Bully diet is complete, balanced, appropriate to the life stage, and fed in the right quantity. The format matters much less than people think: kibble, raw and home cooked can all be done well or badly. What decides the outcome is whether it’s nutritionally complete and whether the dog stays lean.
The three formats, honestly
Commercial kibble
The default, and there’s nothing wrong with it. Convenient, storable, cheap, and the reputable manufacturers formulate to a standard and run feeding trials. Look for the AAFCO statement and a named meat.
Downside: quality varies enormously across the price range, and the marketing on the bag is largely unregulated.
Raw
Can be excellent and can be a disaster. A properly formulated raw diet is balanced across muscle meat, organ, bone and supplementation. An improvised one is usually short on calcium, or wrong on the calcium to phosphorus ratio, which does lasting skeletal harm to a growing large-breed dog.
Downside: bacterial risk to the dog and to anyone in the house handling it, cost, freezer space, and the need to actually get the formulation right. Use a veterinary nutritionist, not a Facebook group.
Home cooked
Total control over ingredients, which genuinely helps a dog with confirmed food allergy. Almost always nutritionally incomplete unless formulated by a professional, because the gaps are in vitamins and minerals you can’t see.
What a balanced diet has to contain
| Component | Why | Watch for |
|---|---|---|
| Protein | Muscle maintenance and repair | 22 to 30% adult, higher for puppies |
| Fat | Energy and coat condition | Too little dulls the coat, too much adds weight fast |
| Calcium and phosphorus | Skeletal development | The ratio matters more than the amount in a growing large breed |
| Omega-3 | Skin, coat, joints | A named fish source. Worth adding for this breed |
| Fibre | Gut function | Usually adequate. Adjust if stools are consistently loose |
| Vitamins and minerals | Everything else | The reason home cooked needs formulating |
Supplements: what’s worth it
Worth it: omega-3 fish oil, for a breed that gets skin trouble. Joint support with glucosamine and chondroitin for an older or a very heavy dog, where the evidence is modest but the downside is nil. A probiotic during and after antibiotics.
Not worth it for a dog on a complete food: multivitamins, which risk oversupplying fat-soluble vitamins. Anything marketed as a muscle builder. Calcium supplements for a growing puppy, which actively cause harm by disrupting the ratio the food already got right.
The commonest and most damaging supplement mistake in this breed is adding calcium to a large-breed puppy’s diet in the belief it builds bone. It does the opposite: it disrupts normal skeletal development during the window when the growth plates are open. If the food is a complete large-breed growth formula, it already has what the puppy needs.
Feeding for the dog in front of you
Whatever the format, the measure of success is body condition rather than what’s in the bowl. Ribs findable under a thin layer with flat fingers. A visible waist from above. A tuck from the side. Check every couple of weeks with your hands, because the change is too gradual to see.
