What is Leash Reactivity?

I will explain to you guys what I believe is the most important part regarding this matter of leash reactivity. | believe it's a relationship issue. I want my dog to know a few things. Firstly, I want my dog to trust me enough to know I'll protect them so they don't have to protect yourself. Two, I want to be more important than anything else outside. Think of how little we mean to our dogs when a dog, person or squirrel enters the proximity and your dog explodes. I want my dog to know I can help handle stressful situations so they don't have to. I believe in doing so I build trust with my dog.
