“ Occasionally, a dog will be presented as some training method for having a baby. My girlfriend and I got a dog. We are going to see if we can handle that before we have kids. This is a little like testing the waters of being a vegetarian by having lettuce on your burger. Okay, maybe that metaphor doesn't make sense, but neither does using a dog as a training method for having a baby. ”
