First, a warning: if you are having difficulty raising a puppy with good manners, you are not yet ready to train a service dog. To train a service dog you should already have skills sufficient to title a dog in obedience. This isn't something you can just learn as you go along because it takes years to master.
However, we do get a lot of questions from kids and others who are just curious about what service dogs are and what they do, perhaps for a school report, but also have questions about their own pet dogs. For them we've included some very basic pet dog training tips we've gathered over the years.
