10 Dog Training Myths That Are Keeping Your Dog Stuck

Back to Blog

Bad information travels fast — especially about dog training. A lot of what gets passed around as "common knowledge" is not just wrong, it is actively damaging. I've sat across from hundreds of frustrated dog owners whose problems were made worse by myths they picked up from the internet, from well-meaning friends, or from trainers who should have known better.

I'm André at Unleash'd K9 in North Miami. Let's go through the ten myths I hear most often — and what is actually true instead.

Myth 1: You Can't Teach an Old Dog New Tricks

This one has been holding people back for decades. The truth is that adult dogs are often easier to train than puppies. They have longer attention spans, they are past the distraction-heavy developmental phases, and they are not fighting the impulse control issues that make puppies so inconsistent.

What is true is that some behaviors take longer to change in adult dogs because they have more repetitions of the old behavior reinforced. But "longer" is not "impossible." I have trained dogs well into their senior years to have new skills, new boundaries, and new levels of reliability. Age is not the variable. Consistency and method are.

Myth 2: My Dog Knows What They Did Wrong

You come home to a chewed-up couch. Your dog slinks toward you, head low, tail tucked, eyes averted. They look guilty. They know, right?

No. What you are seeing is a dog responding to your body language and the context of the situation, not to the memory of a past act. Dogs do not have the cognitive ability to connect a behavior from two hours ago to your current emotional state. They are reacting to the fact that you walked in, scanned the room, and your energy shifted. They learned: when the human comes home and looks like this, bad things happen. That is not guilt — that is conditioned fear.

Punishing a dog for something they did in the past teaches them nothing about the behavior. It only teaches them that your arrival is sometimes dangerous. If you want to stop the chewing, manage the environment and train an incompatible behavior — not punish the innocent face that greets you at the door.

Myth 3: Dominant Dogs Need to Be Dominated Back

The dominance theory of dog behavior — the idea that dogs are always trying to "rank up" and that owners must assert alpha status — has been thoroughly discredited. The original research it came from was conducted on captive, unrelated wolves under stress, and those researchers themselves have walked back those conclusions.

Dogs are not plotting a power grab. A dog that jumps on you is not trying to dominate you — they are seeking attention and have been reinforced for jumping. A dog that pulls on the leash is not asserting dominance — they have learned that pulling gets them where they want to go. These are learned behaviors, not status challenges. Treating them as status challenges leads to confrontational methods that damage trust and often make behavior worse.

Myth 4: Positive-Only Training Is Always the Kindest Approach

I believe in reward-based training. I use it every day. But "positive-only" as a rigid philosophy — the idea that no dog should ever experience any consequence or correction — does not hold up in practice, especially for serious behavior issues.

Kindness means giving your dog clear communication, consistent expectations, and the information they need to make good decisions. Sometimes that information includes a correction. A dog charging toward traffic needs more than a treat to stop. A dog with a bite history needs more than ignoring bad behavior and rewarding good. Using every tool available to communicate clearly — while prioritizing the dog's wellbeing — is what a balanced approach actually means. The dogma of never using any consequence is not kindness; it is a limitation that fails dogs when they need real help.

Myth 5: My Dog Just Wants to Please Me

Dogs are motivated by what works for them — food, play, social connection, environmental access. They do not have an intrinsic drive to make you happy independent of what that gets them. When a dog "does something to please you," they are doing something that has been reinforced in ways that feel good to the dog.

This matters because it changes how you train. If you assume your dog is trying to please you and they do not comply, you conclude they are being stubborn or defiant. If you understand that behavior follows consequence, you ask a different question: what is motivating this dog right now, and how do I make the behavior I want more valuable than the behavior I am seeing?

Myth 6: Small Dogs Don't Need Training

A 10-pound dog that jumps, barks incessantly, snaps, and never walks on a loose leash is a problem dog — just a small one. Small dog owners often normalize behaviors in their dogs that would be immediately addressed in a larger breed, simply because the physical consequences are less dramatic.

But the dog is still stressed. The household is still chaotic. And those "cute" behaviors frequently escalate. The small dogs I work with often have some of the most significant confidence and anxiety issues I see, precisely because they were never given structure, leadership, or rules that helped them feel secure. Every dog deserves training. Size changes nothing.

Myth 7: The Breed Determines Everything

Breed influences temperament, drive level, energy, and predispositions. It does not determine outcome. I have worked with "aggressive breeds" that were gentle family dogs and "family breeds" with serious behavioral issues. Genetics loads the gun; environment and training pull the trigger.

Using breed as an excuse — "pit bulls are just aggressive" or "labs are just naturally perfect" — removes your responsibility as a trainer and owner. Your dog is an individual. Learn that individual, address their specific drives and tendencies, and train accordingly.

Myth 8: Rubbing Their Nose in It Teaches a Lesson

This method is decades out of date and it does not work. A dog that is physically confronted with a mess they made hours ago does not connect the punishment to the act — they connect the punishment to your presence near that spot. The result is a dog that hides to eliminate, or becomes anxious around you, not a dog that understands "don't potty inside."

Effective housetraining is about management, supervision, and rewarding the dog for going in the right place consistently. If your dog is having accidents, the answer is more supervision, a better schedule, and positive reinforcement when they get it right — not punishment after the fact.

Myth 9: "He Did It Once, So He'll Do It Again" About Aggression

An aggression incident does not define a dog's future — but it does demand an honest response. The myth is not that aggression can be rehabbed (it often can), it is the fatalistic assumption in both directions: that one incident means the dog is broken beyond repair, or alternatively that one incident means nothing and requires no intervention.

Every aggression incident needs to be taken seriously and assessed in context. What was the trigger? How severe was the bite? What does the pattern look like? A fear-based snap from an under-socialized dog in a specific situation is very different from unpredictable aggression in a dog with no history. Get a professional assessment. Do not write the dog off and do not dismiss it.

Myth 10: My Dog Will Grow Out of It

This is the myth that costs owners the most time. A puppy that jumps, pulls, and ignores commands does not grow out of those behaviors — those behaviors grow with the dog, become more reinforced, and get harder to change. An anxious puppy that is not properly socialized during the critical window does not become a confident adult. They become an anxious adult with a longer history of that anxiety being reinforced.

Time does not fix behavior. Training fixes behavior. The longer you wait, the more you are reinforcing the problem and the harder the fix becomes.

If you recognize a problem — whether your dog is 4 months or 4 years old — start now. Every week you wait is more practice at the wrong behavior. Start the right training today.
