Чем немецкие собаки отличаются от украинских?

German dogs are calm and peaceful. But our dogs only dream of peace. Why are our dogs so anxious, wary, distrustful, and unfriendly? Why, like wolves, do they gather in packs, behave aggressively, and even bite? Why do they bark at someone, then howl at something? What do they lack? Why are they so angry? Where's the problem? Is the dog being killed? Are people to blame? But we have good people. What's wrong with our dogs?
