Big feelings, not bad dogs
Reactivity is an over-the-top response (barking, lunging, growling, spinning) to a trigger such as other dogs, people, bikes or cars. It is usually driven by fear or frustration (wanting to greet and being held back), and it is not the same as aggression, though it can overlap.
Reactivity often has contributing factors: genetics, limited socialization, past scary experiences and pain. A vet check is an important first step, because pain makes dogs more irritable. If your dog has bitten, or you feel unsafe, work with a qualified behavior professional or veterinary behaviorist.
Key takeaways
- Reactivity is an emotional overreaction, often fear or frustration.
- Rule out pain with a vet check first.
- Bites or safety concerns call for a qualified professional.
Training session: Reactivity journal
- For one week, record each reaction: trigger, distance, behavior, duration.
- Note the time of day and how your dog slept.
- Book a vet check to rule out pain.
- Identify your dog’s top three triggers.
Troubleshooting: If reactions are severe or getting worse, contact a certified behavior professional now rather than later.
