When Your Dog's Prey Drive Kicks In
That moment when your dog's eyes lock onto a squirrel, cat, or jogger and everything else disappears — their body goes still, then explodes into chase mode. You're witnessing ancient programming in action.
Understanding the Predatory Sequence
Predatory behavior follows a predictable pattern: orient, stalk, chase, grab, and sometimes consume. Some dogs move through the entire sequence; others repeat just one or two steps, depending on genetics and learned experience. A Border Collie might excel at the eye-and-stalk portion, while a Greyhound might skip straight to the chase. The key insight: this isn't aggression or disobedience. It's a hardwired behavioral chain that feels deeply rewarding to your dog.
The trigger is almost always movement. Small, fast-moving objects activate the sequence most reliably. High-pitched sounds can intensify the response. Once the sequence starts, your dog's ability to hear you drops sharply. They're not ignoring you; they're neurologically focused on prey.
Target Behavior: Controlled Attention
Instead of fighting prey drive, you can redirect it. The target behavior here is your dog orienting to you when they spot potential prey, before the full sequence takes over. This creates a window to manage the situation and offer healthy outlets for that drive.
1
Build Attention Around Mild Triggers
Start 50 or more feet from where squirrels appear, or use a window where your dog can see movement but isn't aroused enough to chase. The moment your dog notices but before they fixate, mark and reward their attention back to you. Practice this distance until you get reliable check-ins.
2
Teach "Leave It" with Movement
Roll a ball across the floor. When your dog looks at it but doesn't chase, mark and reward. Build up to dropped food, then thrown toys they must ignore. The dog learns that stillness in the presence of moving objects gets reinforced, while chasing gets nothing.
3
Set Up Controlled Encounters
Use a 50-foot long line in areas where prey animals appear. When your dog orients toward a squirrel or cat, call them once. If they respond, mark and deliver extraordinary reinforcement — their best treats or immediate access to sniffing or exploring. If they don't respond, calmly prevent the chase with the long line. Skip punishment.
4
Provide Appropriate Outlets
Satisfy the drive through games that mimic hunting: hide treats for your dog to find, use food puzzles, play tug, or practice flirt pole exercises. A dog whose prey drive gets appropriate expression is less likely to explode when they see the neighbor's cat.
Management: Your Safety Net
While you build these skills, antecedent arrangement is your safety net. Dogs get better at behaviors they practice — including chasing. Use baby gates to block visual access to windows where prey animals appear. Walk your dog on a leash or long line in any area where they might encounter cats, squirrels, or small dogs until your recall is reliable in those contexts.
Why Punishment Fails Here
Prey drive is intrinsically rewarding. The chase itself feels good to your dog. Trying to interrupt it with corrections often just adds arousal to an already exciting situation. You'll get faster, sneakier chasing rather than impulse control. Focus on teaching the dog what TO do instead.
Differential Reinforcement Strategy
Here, you're using differential reinforcement of alternative behavior (DRA). The problem behavior is chasing; the alternative is orienting to you. Both serve the same function — excitement, arousal, and reward. By making attention to you more rewarding than the chase (through timing and high-value reinforcement), you shift your dog's choice in the moment.
Track your progress with simple data: count how many times per walk your dog notices potential prey and chooses to check in with you instead of fixating. Start with a goal of 3 out of 10 encounters, then build toward 8 out of 10. This gives you concrete feedback on whether your training is working.
Every Dog Is Different
The right approach depends on why your dog does this — and that varies by temperament, history, and environment. The Synchrony coach can tailor these principles to your dog's specific behavior profile.
