Training an American Bully
A strong, willing, food-driven dog that’s easy to train and genuinely hard to manage if you skip the first year.
American Bullies are straightforward to train: people-oriented, food-motivated and eager to please. The difficulty isn’t temperament, it’s physics. A dog that was never taught not to pull is a minor nuisance at fifteen pounds and a real problem at seventy, so loose-lead work from twelve weeks matters more with this breed than with most.
The first year, in order of priority
1. Socialisation, and the window closes
The critical period runs to roughly sixteen weeks. The AVSAB position statement is the reference. What a puppy meets calmly in that window it accepts for life; what it doesn’t meet it may find alarming later. My puppies leave at nine to twelve weeks already used to a household, but the rest is yours and it’s time-limited.
Aim for variety rather than volume: different surfaces, different people, traffic, other calm dogs, vet visits that involve nothing but a treat. Keep every experience good. One frightening encounter in this window does more damage than ten neutral ones do good.
2. Loose lead, before the dog is strong
Start at twelve weeks in the house. The rule that works is simple and unglamorous: the lead going tight means I stop. Not a correction, just a full stop, every time, until the dog works out that pulling ends the walk.
Use a flat collar or a harness. Never a retractable lead on a strong breed: it teaches constant tension, which is the exact thing you’re trying to untrain.
3. Recall, on a long line
Build it on a fifteen-metre line before you ever trust it off-lead. Never call a dog to punish it and never call when you aren’t confident it will come, because every failed recall makes the word mean less.
4. Settle
Underrated and the one that makes a big dog liveable. Teaching a bully to lie down and switch off on a mat is worth more day to day than any trick.
What this breed responds to
Reward-based training, without qualification. That is where the veterinary behaviour profession sits on it. This isn’t a soft opinion, it’s where the evidence sits: aversive methods produce more stress-related behaviour and no better obedience. On a breed already carrying an unfair reputation, a dog trained through intimidation is also a genuine liability.
Bullies are food-driven, which makes them easy. Keep sessions to five minutes, several times a day, and end while the dog is still interested. Count the training treats in the daily food allowance or you’ll have a fat dog by six months.
The three problems I get asked about most
| Problem | Why it happens | What works |
|---|---|---|
| Pulling on the lead | Pulling got the dog where it wanted to go | Stop dead every time the lead tightens. Be boring and consistent |
| Jumping up at people | It was rewarded with attention as a puppy | Turn away, no eye contact, reward four feet on the floor |
| Chewing, 4 to 7 months | Teething, and boredom | Frozen chews, rotate toys, manage the environment rather than punish |
Note what all three have in common: they’re normal behaviour that got reinforced, not defiance. A bully isn’t trying to establish rank over you, whatever the internet says about dominance.
Worth paying for a class
A puppy class is a hundred to three hundred dollars and it’s the best money you’ll spend in the first year, mostly for the socialisation with other dogs under supervision. Find one that’s reward-based and ask what they do when a dog gets it wrong. If the answer involves a correction, find another.
Two other things worth knowing about this breed specifically: dog-to-dog tolerance can narrow as a bully matures, usually between one and three years and often with same-sex dogs. That’s normal, it isn’t a training failure, and it’s managed with honest expectations rather than surprise. And strength is separate from intent: a delighted seventy-pound dog can knock a child over with no aggression whatever.
Puppies raised in the house, not in a run
They arrive already used to noise, people and children, which is the part of socialisation you can’t do afterwards.
