<human>: What do I need to know before I buy a dog?
<bot>: Before you buy a dog, it is important to consider the size of your living space, whether or not you have children and if they will be able to take care of a puppy, how much time you can commit to training and caring for the dog, and what type of activities you plan on doing with the dog. Additionally, research the breed of dog you are interested in and make sure that you understand any potential health concerns associated with that particular breed.
