I want to get a dog... does anyone here have a dog?

Male or female, xD? It's called a dog and a bitch. Get an Asian breed; it will definitely attack bullies, but it's very difficult to train, and if something happens, it might even attack you. I have a Newfoundland; it's beautiful, kind, and big. It eats a lot and is very smart. Because of the latter, I sometimes even feel insecure. However, you probably won't be able to set it on bullies because the dog isn't aggressive.
