Dog Reactive Only to Small Dogs? Here's What's Going On
Why dogs react to small dogs, and a calm, step-by-step plan to help yours, from the CalmWalk team.
Why it happens
Some dogs react to small dogs because they move fast, bark a lot or trigger prey-like interest. Others had a bad experience with a small dog that was never corrected.
What to do, step by step
- Take it seriously: size differences make incidents risky.
- Work at a distance from small dogs specifically.
- Reward calm looks and disengagement.
- Avoid off-leash areas where small dogs run up.
- Consider muzzle training if there's any predatory behavior.
The 4 steps that work for most reactive dogs
- Stop the daily blow-ups first. Walk at quieter times, on routes with wide views, and swap some walks for sniff walks. Why this matters.
- Find your dog's safe distance, where it can notice a dog and still take a treat. The 10-minute distance test.
- Teach a few simple skills at home: a marker word, name-turn, hand touch and an emergency U-turn.
- Make other dogs predict good things with short "Look at That" sessions. Step-by-step guide.
