P is for Prey Drive
Why Sighthounds Chase (and Why You Can't Stop It)
Your sighthound is lying on the sofa. Completely still. Eyes half closed. The picture of lazy contentment. And then, through the window, a pigeon lands on the garden fence.
Everything changes. The eyes snap open. The body goes rigid. Every muscle tightens. The ears lock forward. There's a low tremor through the whole frame, a coiled spring that wasn't there a second ago. If there was a door open, they'd be through it before you finished your tea.
That's prey drive. And if you own a sighthound, you need to understand it.
What prey drive actually is
Prey drive is an instinctive urge to chase, catch and sometimes kill small, fast-moving animals. It's not learned behaviour. It's not aggression. It's not excitement that's gone too far. It's a hardwired biological response that's been selectively bred into sighthounds for centuries.
Sighthounds hunt by sight. Their field of vision is wider than most breeds. They detect movement at distances that would be invisible to a Labrador. And when they see something that triggers the sequence, the response is involuntary. Brain says chase. Body obeys. Everything else, including you, your voice and your treats, ceases to exist.
This is what they were bred to do. Greyhounds chased hares. Whippets chased rabbits. Lurchers were bred as all-purpose hunting dogs. The modern pet sighthound still carries that programming, even if the only thing they're chasing is a leaf in the wind.
Why you can't train it out
This is the part people struggle with. Because it sounds like a problem that should have a solution. But prey drive isn't a behaviour. It's an instinct. You can't train it out any more than you can train a cat not to stalk or a bird not to fly.
You can teach your sighthound to sit, stay, walk nicely on a lead and come back when called in low-distraction environments. All of that is achievable. But the moment a genuine prey trigger fires, a real squirrel, a real cat, a real rabbit, training takes a back seat to biology.
Some sighthounds have low prey drive. They'll see a cat and barely react. Others have sky-high drive and will fixate on anything that moves. Most sit somewhere in between. Knowing where your individual dog lands on that spectrum is essential.
How to spot it
You'll know when prey drive activates. The signs are unmistakable.
Fixation: They lock onto something and won't look away. Their gaze is hard, focused and unblinking. You can call their name and get nothing. They're not ignoring you. They genuinely can't hear you.
Stillness: Before the chase, there's often a freeze. The body goes rigid. The muscles tense. They're loading up.
Trembling: Some sighthounds tremble or vibrate when prey drive is triggered. It's the adrenaline building.
Lunging: If on a lead, they'll pull hard, often silently, towards the target. The force can catch you off guard. A 30kg greyhound hitting the end of a lead with intent is no small thing.
The chase: If off lead, they're gone. Full speed, no hesitation, no recall. The chase itself can be completely silent. No barking. Just speed.
What triggers it
The obvious ones: cats, squirrels, rabbits, small dogs, birds on the ground. But prey drive can fire on less obvious triggers too.
Plastic bags blowing in the wind.
Joggers (especially in the distance, where motion is detected before identity).
Cyclists.
Children running.
Balls, frisbees and toys moving at speed.
Other dogs running, particularly small ones.
The trigger is movement, not the animal itself. Anything that moves fast and erratically can activate the response. A stationary cat might get a glance. A running cat gets a chase.
Managing prey drive
You can't eliminate it, but you can manage it. Management is about controlling the environment so the instinct doesn't get the chance to cause harm.
On-lead walking: The default until you know your hound's prey drive level. Our off-lead guide covers this in detail.
Muzzles: A muzzle doesn't stop the chase, but it prevents harm at the end of it. Our muzzle guide covers types and fitting.
Awareness: Scan the environment constantly. If you see a cat ahead, cross the road. If there's a rabbit in the field, change direction. Prevention is easier than reaction.
Secure garden: Check your fencing regularly. A sighthound motivated by prey drive can clear a fence you'd swear was high enough. Six feet is the commonly recommended minimum for greyhounds.
Controlled outlets: Lure coursing events, secure field hires and flirt poles in the garden give sighthounds a chance to express chase behaviour safely. These aren't a cure for prey drive, but they satisfy the urge in a controlled way.
Living with it honestly
The hardest part of prey drive isn't managing it. It's accepting it.
It means your greyhound might never be off lead in an open park. It means your lurcher might never live with a cat. It means watching your whippet fixate on a squirrel and knowing that if you let go of the lead, everything changes.
That's not a failure. It's reality. And a sighthound whose prey drive is honestly assessed and properly managed is safer, happier and better understood than one whose owner pretends it isn't there.
They chase because that's who they are. Love them for it. Manage around it. And keep a firm grip on the lead.
