Predatory Chasing: Managing Prey Drive Safely

One second the walk is going fine. The next, your dog has locked onto a magpie across the oval and you’re being dragged at full speed with the lead burning through your hands. Or worse — the dog spots the neighbour’s cat and every command you’ve ever taught evaporates in a blur of tunnel-vision pursuit.

Prey drive is one of the most hardwired behaviours in dogs, and one of the hardest to override once the chase begins. You can’t train it out of a dog entirely — it’s instinct, not disobedience. But you can manage it, redirect it, and reduce the risk of a dangerous incident. This guide covers what prey drive actually is, why some dogs are more driven than others, and the practical steps that keep cats, wildlife, and your dog safe.

Prey drive is a dog’s natural instinct to search, stalk, chase, and capture moving things. It’s strongest in terriers, sighthounds, herding breeds, and hunting breeds, but any dog can show it. You can’t eliminate prey drive, but you can manage it with a solid recall, “leave it” training, a long line for safety, environmental management (secure fencing, on-lead walks), and by giving the dog outlets like flirt poles, fetch, and scent games. In Australia, a dog that chases livestock or injures another animal can result in fines, dangerous dog declarations, or worse. Prevention is everything.

What Is Prey Drive?

Prey drive is a dog’s instinctive desire to detect, pursue, and capture moving objects. It’s a survival behaviour inherited from wolves and refined by centuries of selective breeding. The full predatory sequence runs through several stages: searching (scanning the environment), stalking (creeping towards the target), chasing, grab-biting, kill-biting, and consuming.

Most domestic dogs don’t run the complete sequence. A Labrador retrieves but doesn’t kill. A Border Collie stalks and controls sheep without biting. A Greyhound chases at full speed but many never catch live prey. Selective breeding has amplified some parts of the sequence and dampened others depending on the breed’s original job. But the underlying drive is still there, and when something small, furry, or fast-moving crosses a dog’s field of vision, that ancient wiring can switch on in an instant.

Prey drive is not the same as aggression. A dog chasing a possum across the backyard isn’t angry — the dog is locked into a deeply rewarding neurological loop. The chase itself floods the brain with dopamine, which is why it’s so difficult to interrupt once it starts and why dogs will repeat it at every opportunity.

Which Dogs Have the Strongest Prey Drive?

All dogs have some degree of prey drive, but certain breed groups were developed specifically for hunting, chasing, or controlling other animals.

• Sighthounds (Greyhounds, Whippets, Afghan Hounds) — bred for explosive speed to chase down prey by sight. Retired racing Greyhounds in Australia are increasingly popular as pets, and their chase instinct around small dogs and cats needs careful management.
• Terriers (Jack Russells, Fox Terriers, Australian Terriers, Staffies) — bred to hunt and kill rodents. Terriers often show the full predatory sequence, including grab-bite and shake.
• Herding breeds (Kelpies, Border Collies, Australian Cattle Dogs) — show a modified prey drive that manifests as stalking and chasing to control movement. The bite is often inhibited, but the chase instinct is intense.
• Hunting/sporting breeds (Labradors, Spaniels, Pointers, Beagles) — bred to locate, flush, or retrieve game. Drive is present but often directed toward fetching rather than killing.
• Northern breeds (Huskies, Malamutes) — high prey drive combined with independence. A Husky that spots a rabbit in an unfenced area may be kilometres away before you finish calling the dog’s name.

Low-drive breeds exist too — Bulldogs, Cavalier King Charles Spaniels, and Great Pyrenees tend to be on the calmer end. But individual variation is significant. A low-drive breed can still have a dog with strong chase instincts.

What Triggers the Chase?

Movement is the primary trigger. Fast, erratic, small-animal movement activates the chase instinct far more than a stationary object. Common triggers in Australian environments include:

• Cats — especially neighbourhood cats crossing through the yard or darting across a path.
• Birds — magpies, ibis, lorikeets, and other ground-feeding birds that take off suddenly.
• Possums and other native wildlife — particularly at dusk and dawn.
• Rabbits — common in peri-urban and rural AU areas.
• Lizards, skinks, and small reptiles.
• Joggers, cyclists, and skateboarders — the movement pattern mimics fleeing prey.
• Other small dogs, especially if they run.
• Livestock — sheep, chickens, and ducks on rural or semi-rural properties.

The chase can also be triggered by sounds (rustling in bushes) and scent (fresh animal trails), though visual movement is usually the strongest activator.

Why Prey Drive Is a Safety Issue in Australia

Prey drive becomes a genuine problem when it puts other animals, people, or the dog at risk.

Injury or death to other animals

A dog with strong prey drive can kill a cat, a small dog, or native wildlife in seconds. Possums, bandicoots, and birds are particularly vulnerable in suburban Australian backyards. Wildlife rescuers across Australia regularly treat animals injured by domestic dogs, and this is a preventable problem.

Legal consequences

In every Australian state and territory, owners are legally responsible for their dog’s behaviour. In Victoria, a dog that rushes at, chases, or attacks a person or animal can be declared a “menacing dog” or “dangerous dog,” carrying strict housing, muzzling, and desexing requirements. In Queensland, a dog that attacks livestock can be lawfully destroyed by the property owner. Fines for dog attacks and uncontrolled dogs run into thousands of dollars across all jurisdictions. Check with your local council for the specific rules in your area.

Risk to the dog

A dog in full chase mode is deaf to recall and blind to hazards. Dogs chasing prey across roads get hit by cars. Dogs that corner snakes — common during Australian spring and summer — get bitten. Dogs that chase kangaroos in rural areas can run for kilometres and become lost. The chase is so neurologically rewarding that the dog doesn’t assess risk until it’s too late.

How to Manage Prey Drive Safely

You cannot eliminate prey drive. But you can build reliable management habits and train cues that give you the best possible chance of interrupting the sequence before the dog hits full chase.

Step 1: Prevent the chase from practising

Every successful chase reinforces the behaviour and makes the next one more likely. Management is the first line of defence.

• Keep the dog on lead in unfenced public areas. No exceptions for high-drive dogs.
• Use a long line (five to ten metres) in open spaces for controlled freedom.
• Secure your yard — check fences for gaps, make sure gates latch properly, and consider adding a coyote roller or angled fence extension if the dog jumps.
• Supervise the dog around cats and small pets. Never leave a high-drive dog alone with a cat, regardless of how well they seem to get along. One panicked sprint by the cat can override months of calm coexistence.
• Use a front-clip harness for better steering on walks. Avoid retractable leads — they give you zero control when the dog bolts.

Step 2: Build a rock-solid “leave it”

This is the single most valuable cue for a prey-driven dog. Start with low-value items at home (a treat on the floor covered by your hand), reward the dog for backing off, and gradually work up to higher distractions. Eventually, “leave it” should mean “stop looking at that and check in with me” — whether “that” is a treat on the ground or a bird on the oval.

Step 3: Train recall to compete with the chase

Recall is the emergency brake, but it has to be strong enough to compete with dopamine. Use the highest-value rewards you have (not kibble — roast chicken, cheese, liver treats). Practise recall on a long line in progressively distracting environments. Never recall and then end the fun — recall should mean “come to me for something amazing, then go play again.”

Be realistic: even the best-trained recall will fail when a dog is in full chase mode and dopamine has taken over. That’s why management (lead, long line, secure fencing) is non-negotiable alongside training.

Step 4: Interrupt the sequence early

The earlier you interrupt the predatory sequence, the better your chances. Once the dog is scanning the environment and you spot the trigger first, you can redirect. Once the dog is locked in a hard stare (stalking), it’s harder. Once the dog bolts (chasing), recall is almost impossible. Trainer Joan Harris of PAWS Chicago describes it as “defensive driving” — spot the trigger before your dog does and redirect immediately.

Useful interrupt tools: a cheerful “this way!” with a U-turn, a scatter feed (“find it!” with treats tossed on the ground to bring the dog’s nose down), or a squeaky toy that breaks the visual lock.

Step 5: Give the dog legal outlets

A dog that never gets to chase anything is a frustrated dog. Channel the drive into activities that satisfy the instinct without putting anyone at risk.

• Flirt pole — a pole with a rope and toy attached, used like a giant cat wand. The dog gets to chase, pounce, and “catch” in a controlled setting. Excellent for terriers and high-drive dogs.
• Fetch and tug — both tap into different parts of the predatory sequence (chase, grab, hold) and are easy to do daily.
• Scent work and nose games — scatter feeds, treat trails, and hidden-toy searches engage the search and tracking stages of the sequence without the chase.
• Lure coursing — available at some Australian dog clubs, this lets sighthounds chase a mechanical lure at full speed in a safe, fenced environment.
• Agility and flyball — high-energy dog sports that burn physical and mental energy while building impulse control.

Simone Mueller, author of Hunting Together, describes this approach as Predation Substitute Training — giving dogs the chance to perform safe parts of the predatory sequence through structured games, rather than trying to suppress the instinct entirely.

Living With Cats and Small Pets

Many dogs and cats live together successfully, but the introduction and ongoing management need to be taken seriously when the dog has prey drive.

Start slow. Keep the dog on lead or behind a baby gate for all early interactions. Let the cat observe the dog from a safe, elevated position (a cat tree, a high shelf). Reward the dog heavily for calm behaviour in the cat’s presence. Never let the dog chase the cat “for fun” — even playful chasing rehearses the predatory sequence.

Give the cat escape routes at all times. Cat doors to a dog-free room, high shelves, and baby gates the cat can jump over but the dog can’t are essential. A cat that can’t escape feels trapped, panics, runs — and a running cat is the single strongest prey trigger for a dog.

Never leave a high-drive dog unsupervised with a cat. Dogs and cats that have lived together peacefully for years can still have an incident if the cat suddenly bolts or the dog is startled. Management is a permanent part of the arrangement, not a temporary phase.

When to Get Professional Help

Seek professional guidance if the dog has injured or killed another animal, if the drive is so intense the dog can’t focus on anything else during walks, if the dog lives with cats or small pets and you’re not confident in the management setup, or if recall is completely unreliable around triggers. In Australia, a qualified behaviourist can assess the strength of the drive, design a management and training plan, and determine whether the dog can safely share a home with other animals. Your vet is the best starting point for a referral.
