If you spend five minutes in a modern dog training forum, you will inevitably hit the same tired piece of standard advice: “Don’t let your dog chase that ball, that squirrel, or that flirt pole. If you let them chase, you’re going to create prey drive.”
It is an industry-wide old wives’ tale wrapped in pseudo-scientific concern. It betrays a fundamental misunderstanding of basic canine biology and behavioral genetics.
Let’s get one thing straight: You cannot create an instinct.
The Tapestry of Instinct
Prey drive isn’t a bad habit a dog picks up because you let them have too much fun on a Tuesday afternoon. It is an inherited, hardwired genetic program. It is the predatory motor pattern—orient, eye, stalk, chase, grab-bite, kill-bite—that has been woven into the DNA of Canis lupus familiaris over thousands of years of evolution and deliberate breeding.

You don’t “create” prey drive by letting a dog chase any more than you “create” a Border Collie’s desire to eye sheep or a Pointer’s instinct to freeze at the scent of a bird. The engine is already inside the car. All you are doing by allowing the chase is opening the garage door and letting the vehicle run.
When trainers tell you to stop the chase entirely, what they are actually advocating for is the permanent, unconditional suppression of a biological need. They want you to weld the garage door shut, put a brick on the gas pedal, and hope the engine doesn’t explode.
The Cost of Biological Suppression
Forcing a dog to completely suppress an instinct as primal as prey drive doesn’t make the drive disappear. It just forces the pressure to build.
When a dog is constantly exposed to moving triggers (cars, runners, bikes, squirrels) and is told that their internal wiring must be flatly denied, the neurological frustration builds up. Eventually, that repressed energy leaks out sideways—manifesting as fence-running, obsessive shadow-chasing, barrier frustration, or sudden, explosive displacement aggression.
Heaven forbid we actually let a dog be a dog. Heaven forbid we allow them to express the very architecture of their brain.
The Power of the Somatic Reset
What these trainers miss entirely is the deep, biological necessity of a somatic reset.
When a dog engages in a clean, structured predatory sequence—like chasing a toy on a flirt pole or tracking down a ball—their nervous system experiences a natural, healthy arc.
- The Spike: The visual of the moving object triggers an immediate surge of arousal and focus.
- The Expression: The dog expends massive physical and neurological energy executing the chase.
- The Discharge: The grab-bite occurs, the prey is “captured,” and the brain releases a flood of satisfaction.
This sequence allows the nervous system to fully discharge accumulated stress. It is a biological pressure valve. After a intense, satisfying predatory game, a dog doesn’t turn into a bloodthirsty monster looking for things to kill; they sigh, drop their shoulders, lie down, and sleep. They have achieved a somatic reset. Their nervous system has reset to baseline because the biological loop was allowed to close.

Channel It, Don’t Choke It
The goal of functional dog training shouldn’t be to eradicate instinct; it should be to channel it.
You don’t stop the dog from chasing. You teach them when and what it is appropriate to chase. You put the drive on cue. You use the flirt pole or the toy as the ultimate functional reinforcer, proving to the dog that cooperation with you is the literal key that unlocks their deepest genetic desires.
Stop trying to train the dog out of the dog. Stop treating a hardwired biological blueprint like a behavioral defect. Let them chase, let them bite the toy, and let their nervous system find the peace that only comes from full expression.
