Or am I? Having a pet is a serious commitment. It needs food, it shits, it pees, it barks. If you dont properly train it when it is young, you will have a pretty fucked up dog. Ask yourself before you purchase that cute puppy in the window, are you honestly ready to look aftersomthing else, or are you just trying to fill the void for something else.
ps. dont get a cat. And if you do, shoot it.
