I live in a very crowded place.My frontdoor is almost my neighboursdoor and there are100 frontdoors in my street.All very close.The neighbours from the other side of my street arent further than 3 meters. I socialised my dogs and all goes well but we forget that sometimes we dont know whatheppens next door. I walk trough my street.A door flies open and a mad man comes out runns into me and my dog (because of all the noise i am shocked and react diffrent than normal) than i have a huge problem because my dog realy goes out of his mind.To be anest my gsd is more easy to control than my co just because their power and protection instinct.This is just an example but you can talk about million unexpected things. A friend of my sonn brought him home.He had a broken arm and was crieing so hi friend pushed him inside the door and my gsd bit him just because of the situation. I know dogs can judge pritty well whats right or wrong but we dont know always for sure so how can we expected they can. I am always alert and still things heppen. I need to walk my dogs close to people.Their are people who live crowdy but have a big yard or woods close.Than you can avoid a lot of these things and stil live in a surbun envirement
