Dog Reactive to Big Dogs? Helping a Nervous Dog Feel Safe
Why dogs react to large dogs, and a calm, step-by-step plan to help yours, from the CalmWalk team.
Why it happens
Big dogs can be genuinely scary, especially for small or fearful dogs who've been rushed or rolled. Barking is a way to keep them at a distance.
What to do, step by step
- Respect the fear: keep big dogs far away while you train.
- Reward calm looks at large dogs from a safe distance.
- Avoid parks where big dogs play rough.
- Build confidence with sniff walks and games.
- Practice with a calm, large dog friend at a distance.
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.
