Chasing
Does your dog chase squirrels, deer, cars, your cat, or anything that moves?
What to do today
1. Name the actual situation
Write down what your dog chases, where it happens, how close the trigger is, and what your dog’s body looks like before the chase starts.
2. Prevent the next unsafe rehearsal
Check fences, doors, gates, leash handling, and household separation. Management protects everyone and keeps the dog from practicing the full chase while you teach a safer response.
3. Find the distance where your dog can still respond
Begin far enough away that your dog can notice the trigger and still eat, move with you, or respond to a familiar cue. If your dog is staring hard, leaning forward, ignoring everything, or lunging, give them a break until you can create more distance.
4. Reinforce noticing and turning back
When your dog sees the trigger, mark the moment they look back, soften their body, or move with you. Reward that choice, and leave while your dog is still successful. You’re building a new pattern, not waiting for a chase so you can correct it.
5. Teach escape skills away from the trigger
Practice a fast U-turn, hand target, cheerful recall, and moving with you in easy places. These skills need a strong history before you can expect to rely on them when something triggers your dog to chase.
6. Add DIFFICULTY gradually
Use controlled setups with plenty of distance. Do not use an unprotected cat, wildlife, livestock, or moving vehicle as a training prop.
7. Give YOUR dog safe ways to move and search
Sniffing, food searches, tug, fetch, flirt pole games, and other species-appropriate activities can give many dogs constructive outlets. Choose activities that fit your dog’s health and interests.
Distance is useful information. If your dog cannot respond, the lesson is too difficult right now. Move away and/or allow them some time to reset before asking for more.
Do not test this around real danger
Use secure fences, doors, gates, barriers, and leashes to prevent access to roads, wildlife, livestock, or another household animal. A long line can be useful in an appropriate open area away from traffic when it is attached to a secure, well-fitted harness and handled carefully.
If your dog chases vehicles, has injured or killed an animal, fixates on another pet, escapes confinement, or cannot be physically managed safely, keep everyone securely separated and get individualized help from a qualified reward-based behavior professional. Sudden behavior changes also deserve veterinary attention.
Troubleshooting
My dog chases squirrels or birds on walks
Scan ahead and create distance before the animal is close. Reward your dog for noticing and reconnecting, then move away or change direction. Practice recalls and U-turns somewhere easier so you’re not asking for brand new skills in the hardest moment.
My dog chases a cat in our home
Make sure your cat has dog-free space to decompress, elevated escape routes in every room, and resources your dog cannot access. Use physical separation when you cannot supervise. Work at a distance where your dog can disengage, and get professional help if you see stalking, intense fixation, lunging, or any contact that could harm the cat.
My dog chases or lunges at cars, bikes, or runners
Move training away from the road or path and create much more distance. Use secure equipment and a route with an escape option. Because one mistake can have serious consequences, this is a strong reason to arrange hands-on professional help if you’re feeling unsure.
My dog will not take food when the trigger appears
Your dog may be too close or too aroused to learn. Try moving farther away or using a visual barrier to block their view. End the training session for now if your dog is totally unable to take food that they usually love. A different reward may help later, but first make the setup easier.
Recall works until an animal runs
Build recall through carefully controlled levels of difficulty, and reward generously when your dog turns away from movement. Keep them on leash or in an enclosure where you can easily catch them while you’re working on this, and don’t call them unless you’re very confident they will successfully come. Do not skip from easy practice to an uncontrolled chase.

This gives you a starting point for structured dog-and-cat training. Physical separation and safe escape options still matter whenever you are not actively supervising.

Vehicle chasing needs a safety-first plan. This lesson shows where I begin while keeping distance and secure restraint at the center of the setup.
