When someone reaches out to me about their dog's behavior, they are usually looking for a training solution. They want to know how to stop the barking, the reactivity, the jumping, the pulling, or the anxiety. They are understandably focused on the behavior they can see because that is what is affecting their daily lives.
However, behavior is rarely the first thing I look at.
A dog's behavior is the outward expression of everything happening beneath the surface. It is influenced by their physical health, their nervous system, their emotional experiences, their daily lifestyle, and whether their biological needs are being met. If we focus only on changing behavior without first understanding what is driving it, we risk overlooking the very things preventing that dog from succeeding.
Over the years, I have found myself following the same sequence with nearly every dog I work with. Before I begin asking a dog to change their behavior, I want to know whether they are physically and emotionally capable of doing so.
Step One: Physiology
The first place I start is physiology.
The brain does not function independently from the body. Every emotion, every thought, and every behavior is shaped by what is happening physiologically. A dog living with chronic pain, digestive discomfort, inflammation, nutritional deficiencies, poor sleep, hormonal imbalances, or ongoing physical stress is operating from a very different place than a dog whose body feels healthy and comfortable.
This is why I spend time asking questions that many people are surprised to hear from a dog trainer. What does the dog eat? How much movement do they get each day? Are they spending time outdoors? Do they have healthy digestion? Could they be experiencing pain that has gone unnoticed? Are they being exposed to unnecessary environmental toxins? Are repeated medical interventions affecting how they feel?
None of these questions are separate from behavior because behavior is always occurring within the body. When a dog feels physically unwell, their nervous system becomes more vulnerable to stress, and their ability to cope with the world around them is reduced. Learning becomes more difficult because the body is already using its resources simply to maintain balance.
Step Two: Welfare
Once I have considered physiology, I begin looking at the dog's welfare.
Many of the behavior problems we see today are not purely training problems. They are often the result of a lifestyle that does not adequately meet the needs of a highly adaptable but biologically complex animal. Dogs have evolved alongside us, but they are still dogs. They still have innate needs that cannot simply be trained away.
I want to know whether the dog has opportunities to move freely, spend meaningful time outdoors, explore their environment through their nose, chew, forage, solve problems, rest deeply, and experience moments of genuine choice and agency throughout the day. I also want to know whether they have opportunities to simply exist without constantly being asked to perform, and suppress their natural behaviors.
When these basic welfare needs are consistently neglected, the nervous system often remains in a chronic state of activation. In that state, we can spend countless hours practicing obedience exercises or behavior modification, yet the dog may continue to struggle because we are trying to change the outcome without addressing the underlying cause.
Step Three: Biological Fulfillment
The next layer I consider is biological fulfillment.
Every breed was developed with a purpose, and although dogs now live very different lives than they once did, those instincts have not disappeared. Retrievers still want to carry things. Terriers still enjoy hunting. Herding breeds remain deeply sensitive to movement. Livestock guardian breeds continue to scan their surroundings and make independent decisions.
These instincts are not flaws that need to be eliminated. They are expressions of what the dog was designed to do.
When a dog's natural drives have no healthy outlet, those drives often emerge in ways we find frustrating. Chasing bicycles, barking at passing cars, digging, chewing furniture, or obsessively fixating on movement may simply be instinct searching for expression.
Rather than trying to suppress those instincts, I believe our role is to provide appropriate outlets that allow dogs to express who they are in ways that are compatible with living in our world. When we work with biology instead of against it, behavior often becomes much easier to influence.
Step Four: Regulation, Co-Regulation, and Connection
Only after I have looked at physiology, welfare, and biological fulfillment do I begin thinking about nervous system regulation and connection.
A regulated nervous system is capable of curiosity, flexibility, learning, and recovery. It can experience stress without becoming overwhelmed by it and return to a state of balance afterward. That capacity does not develop through obedience training alone. It develops through repeated experiences of safety, predictability, connection, and co-regulation.
Dogs are profoundly social animals, and much of their emotional regulation occurs within relationships. The quality of our presence, our ability to remain calm during moments of stress, and the connection we build with our dogs all contribute to creating an environment where learning can actually take place.
Finally... Behavior Modification
This is where most training programs begin, but in many ways it is the final step rather than the first. Once a dog's body is healthier, their welfare needs are being met, their instincts have appropriate outlets, and their nervous system has greater capacity for regulation, teaching new behaviors becomes significantly easier.
Recall training becomes more successful. Reactivity work progresses more smoothly. Impulse control develops with less frustration. Dogs become more resilient, not because we forced them to suppress unwanted behaviors, but because we addressed the conditions that made those behaviors necessary in the first place.
I often think of behavior as the roof of a house. It is the part everyone notices because it is visible, but the roof can only be as strong as the foundation supporting it. Physiology forms the foundation. Welfare builds upon that. Biological fulfillment creates stability, and regulation and connection strengthen the entire structure. Behavior sits at the very top.
If we ignore the foundation and focus only on repairing the roof, we may see temporary improvements, but those changes are often fragile because the underlying structure has never been reinforced.
When we begin with the dog's body, respect their biological needs, and create the conditions in which they can truly thrive, behavior change is no longer something we have to force. Instead, it becomes a natural result of a healthier, more fulfilled, and more regulated dog.
Perhaps the most important shift we can make is to stop asking, "How do I stop this behavior?" and begin asking, "What might this behavior be telling me about what this dog needs?"
When we learn to ask that question first, we stop seeing behavior as the problem and begin seeing it as valuable information. From that perspective, training is no longer about controlling the dog. It becomes an ongoing process of supporting the whole animal, and meaningful behavior change can unfold naturally from there.
