CHASING THE CAT
SAFETY FIRST, THEN CALM

Why dogs chase

Chasing is part of a predatory sequence that dogs inherit: watch, stalk, chase, grab. Different breeds carry different parts of it. Herding dogs often stare and chase. Terriers and sighthounds often chase and grab. Movement is the trigger, and a running cat is the best movement there is.

The chase also feeds itself. Running is exciting, and a cat's flight makes the dog more aroused. If you want more on that, see terriers and prey drive.

Not every dog who chases wants to hurt the cat. Some are playing, and some are scared. But the cat cannot tell the difference, and a fast chase can lead to injury. Take it seriously.

Keep the cat safe first

Before training, make a safe space for the cat and separate the animals when you cannot supervise.

• Give the cat vertical space: cat trees, shelves, a high perch the dog cannot reach.
• Put the cat's food, water and litter box where the dog cannot go. A baby gate with a cat-sized gap or a door latch works.
• Keep the dog on a leash or behind a gate when the cat is out.
• Never leave the two alone together until you are very sure. This can take months.
• Do not force interactions. A cat who feels trapped may swat, and an upset cat makes the dog more excited.

If your dog has caught or hurt a cat, treat this as serious. Keep them completely separate and talk to a professional before any further contact.

Signs your dog is locked on

Watch for a still body, a hard stare, a closed mouth, a lowered head and a stiff tail. These mean the dog is in stalk mode and not available for training in that moment. Calmly increase distance or put a barrier between the animals and give the dog time to come down. Do not scold. A dog who is scolded while stalking may link the cat to trouble, which can add frustration to the chase.

Look at the cat's body, too. A cat who flattens their ears, puffs their tail or hisses is telling you the setup is too close. Respect that, and keep your cat comfortable. The cat should always have a way out.

Teach calm around movement

Start with the cat out of reach, such as behind a gate or on a high perch. The dog is on a leash.

1. Reward the dog for any look away from the cat. Say "yes" and toss a treat on the floor behind them. The treat pulls their head away.
2. Wait for the dog to glance at the cat and glance back. Pay each one.
3. Sit or stand farther away if the dog stares, stiffens, or whines. Distance is your tool.
4. Slowly shorten the distance over many sessions.

This is desensitization mixed with counterconditioning. The cat becomes a cue to look at you, not a cue to chase. Keep each session to two to five minutes. End before the dog gets worked up.

Build impulse control away from the cat

Games that teach the dog to wait for a release help everywhere. Try these.

• Wait at the food bowl until released.
• Drop a toy and wait for "take it."
• Play "Leave it" with treats on the floor under your hand, then slowly uncover them.
• Toss a toy in front of the dog on a leash and ask for a sit before you release.

Practice with moving things the dog likes, like a rolling ball, a flirt pole with a stop cue, or a skittering toy. Reward the dog for waiting and for looking at you. The skill carries over to the cat, but you will always need management as well.

Use the nose

Nose games give chase-driven dogs a legal job. A search channels the hunting drive into sniffing, which is calmer than running. Read scent work for high drive dogs and start nose work at home.

A practical routine is the "cat TV" session. Once a day, bring the dog on a leash into a room where the cat is calmly on a perch or behind a screen. Sit with a handful of treats. Each time the dog looks at the cat and then at you, mark and reward. Each time the dog stares, wait. If the stare breaks, reward. If it does not, add distance. After a minute or two, calmly leave the room together.

Practice makes a calm habit. Do this daily for a few weeks. Over time the dog should be able to sit next to the cat's perch and ignore the cat for a short stretch. It does not mean the dog is safe unsupervised. It means the dog can make a calm choice with your help.

A realistic timeline

Plan for months of management. Some dogs learn to live peacefully with a cat. Others always need supervision, and that is okay. If your dog freezes, stares, lunges or goes stiff when they see the cat, those are signs of high arousal. Slow the plan and get support. Never trust a dog who has hurt a cat to be alone with one.

Introducing a new cat is a separate process. See introducing a dog to a cat for how to do it step by step.

When to get help

Call a trainer if the dog has caught the cat, locks on and cannot be redirected, or if the cat is living in fear. A private lesson can help you set up a safe plan in your own home. We do not use shock collars or other pain to stop chasing, since they add fear and confusion. Our force-free approach builds the dog's ability to choose calm.
