No, you really don't. You may want a dog that protects you and your family, but you don't want a mean dog.
What type of dog you want.
When the owner say "Dog you out" they want the dog to go outside, or out of the room that they are not supose to be in or the owner is in there and does not want the dog in that room. That is why the owner or someone will say "Dog you out"
I want a hot dog
There are no vaccinations that would make a dog mean. A shot from a gun hitting the dog might make it mean if it did not kill it outright but there would a lot of suffering too and I am sure you don't want that. Do you want your dog to be mean? If you do then owning a pet is not for you and I suggest you find a much better home for him or her. Maybe you are wondering why your dog got mean? Is that it? Then please rephrase your question.
a dog is a animal that turns into people pets and when they get old they do not want to be bother with no body
There's no surefire reason your dog would be staring at you constantly. Have you tried feeding him/her? Playing? Normally it means that your dog expects something of you, so if you want him/her to stop, try playing or doing something that your dog would normally want or want to do.
You Want A Hotdog :D
It could be the dog is tired. Is the dog old? You might want to get it checked at a vet.
i do not want to be the bearer of bad news but a black dog normally signifies death
It means your a dog...
If it's for dog fighting, that is a very, very bad idea. Why do even want to make your dog mean?
No, the way a dog is brought up makes it mean, not what it eats.
