Key Takeaways
- Dominance theory has been largely debunked by modern animal behavior research.
- Punishment-based methods can suppress behavior but often increase fear and anxiety in dogs.
- Older dogs are fully capable of learning new behaviors with consistent, positive training.
- Rubbing a dog's nose in an accident is ineffective and can damage your bond.

Why Dog Training Myths Persist
Dog training advice is everywhere — from neighbors to social media videos — and not all of it is grounded in science. Many of the most widely repeated training beliefs were popularized decades ago, long before researchers developed a clearer picture of how dogs actually learn. The result is that well-meaning owners sometimes apply methods that are ineffective at best and harmful at worst.
Just as outdated assumptions affect other areas of life — from common therapy misconceptions to small pet care myths — dog training is full of ideas that don't hold up to scrutiny. Below, we address the most common misconceptions and replace them with what the evidence actually supports.
Myth
Dogs misbehave because they're trying to dominate their owners and establish control in the household.
Fact
Dogs do not scheme to assert dominance over humans. Problematic behavior is almost always rooted in anxiety, boredom, insufficient training, or unmet needs.
The dominance theory of dog training — popularized largely by mid-20th-century research on captive wolves — has been significantly revised by modern behavioral science. Studies on free-ranging wolves and domestic dogs show that social hierarchies are far more fluid and context-dependent than originally understood. The American Veterinary Society of Animal Behavior (AVSAB) has issued a position statement discouraging dominance-based training methods, noting they can increase fear and aggression. When a dog steals food, ignores commands, or jumps on guests, these are behavioral patterns reinforced over time, not power plays.
Myth
You can't teach an old dog new tricks — adult and senior dogs are too set in their ways to learn.
Fact
Dogs of any age can learn new behaviors. Adult dogs often have longer attention spans and are less easily distracted than puppies, which can actually work in a trainer's favor.
This myth likely stems from the observation that puppies seem to absorb everything quickly during their early socialization window. While it's true that early experiences shape a dog's temperament significantly, learning itself is not age-limited. The brain retains plasticity throughout a dog's life, and with the right motivators and consistent repetition, older dogs can master new commands, modify long-standing habits, and even address behavioral challenges. Patience and appropriate reward selection — not the dog's age — are the limiting factors for most owners.
Myth
Rubbing a dog's nose in an accident teaches them not to eliminate indoors.
Fact
This method is ineffective and counterproductive. Dogs cannot connect the punishment to a past action, and the approach often creates anxiety and confusion rather than understanding.
Dogs live largely in the present. Unless a consequence follows a behavior within a second or two, they cannot reliably link the two events. A dog whose nose is rubbed in an old accident is more likely to learn that their owner becomes frightening near that spot than to understand that eliminating indoors is the problem. This type of punishment can make dogs fearful of their owners and may cause them to seek hidden spots to eliminate rather than signaling at the door. Consistent scheduling, positive reinforcement when they go outside, and close supervision indoors are far more effective housetraining strategies.
Myth
A dog that doesn't obey is being stubborn or spiteful — they know what you want and are choosing to refuse.
Fact
Dogs do not experience spite. Non-compliance is typically the result of unclear communication, insufficient reinforcement, distraction, fear, or a command the dog hasn't fully generalized to the current environment.
Attributing human emotions like spite to dogs — a cognitive process called anthropomorphism — often leads owners to apply harsher corrections when what's actually needed is clearer training. A dog who responds perfectly to "sit" at home but ignores the cue at the park hasn't chosen to be defiant; they simply haven't learned to generalize the behavior across environments. This is called proofing, and it requires deliberate practice in different locations with varying levels of distraction. Increasing motivation through higher-value rewards in challenging environments is far more productive than assuming willful disobedience.
Myth
Physical corrections and punishments are necessary to establish respect and teach dogs right from wrong.
Fact
Research consistently shows that aversive, punishment-based methods can suppress behavior short-term but often increase stress, fear, and aggression over time without addressing the underlying cause.
Studies published in peer-reviewed journals, including research from the University of Porto, have found associations between the use of aversive training methods and increased stress indicators in dogs, as well as lower learning performance. The AVSAB and many other professional bodies recommend reward-based methods as a first-line approach. This doesn't mean boundaries are never set — management tools, redirection, and the removal of rewards for unwanted behavior are all legitimate and humane strategies. The goal is to teach dogs what to do, not simply suppress what they shouldn't.
What Science-Based Training Actually Looks Like
Modern dog training draws on decades of behavioral science, particularly the principles of operant conditioning and classical conditioning. These frameworks help explain how dogs associate actions with outcomes — and why rewarding desired behaviors is so much more reliable than correcting unwanted ones.

Dog owners who use some reward-based methods
A survey published in PLOS ONE found that the majority of dog owners report using positive reinforcement as part of their training approach, though many also combine it with other methods.

Learned words in a trained border collie study
Research published in Behavioural Processes documented dogs capable of learning and retaining large vocabularies of object names, illustrating significant capacity for ongoing learning.
Consistency is arguably the most important factor in any training program. Dogs learn through patterns: when a behavior reliably produces a positive outcome, they repeat it. When owners change the rules — sometimes allowing jumping, sometimes not — dogs receive mixed signals that slow progress considerably. Understanding why certain behaviors happen in the first place is equally valuable. For example, leash pulling is often unintentionally reinforced by owners, making it a training problem with roots in human behavior as much as canine instinct.
When to Consult a Professional
Aggression, severe anxiety, and fear-based behaviors go beyond basic training and require professional assessment. A certified applied animal behaviorist (CAAB) or a veterinary behaviorist can evaluate root causes and develop a safe, individualized plan. Attempting to correct these issues with punishment-based methods at home can significantly worsen them.
