When you get that puppy, ASSUME that it needs to be good with kids even if you don’t have kids. It is your duty to your puppy to make it as adaptable as possible, even if you do not anticipate having children. It is a rare situation where a dog will live its lifetime without a need to interact with a child. Not socializing your puppy may increase the odds that it will bite someone someday. It may be put down because of your failures. Therefore, you MUST make sure that puppy is exposed to many people and situations while it is young enough to adapt easily.
