No, it is no different then raising a child.
I have some sites below that will help you with what needs to be done before Puppy comes home to be a Member of your Family, and what to do after he/she comes home. But.... Remember, A Dog is for Life, do not toss your Dog outside and forget about him/her. The Animal Shelters are full of Dogs that have been thrown away, or abused in some pretty horrific ways because they are no longer cute little Puppies. A puppy is a life time commitment and should always be a vital member of your Family. You wouldn't throw your Child out because he/she is no longer a cute little baby.
Now with that said!
"Before the New Puppy Comes Home"
A new puppy is a big job and commitment, with a lot to do and plan in advance. Most of the preparations are the same for an adult dog as for a puppy.
Whether you are waiting for a planned canine family member from a breeder or scheduling a trip to a shelter to look for one, you’ll want to be ready. It can make the difference between a smooth or rocky start with your new pup, or success or failure.
"House Training Your Puppy"
Crate-training is important for puppies. For one thing, when your dog goes to the groomer every 4 to 8 weeks (if you take her even more often, that would be great) she will spend time in a crate. She will also be crated when she stays at the veterinarian's office. And there may be occasions in your care at home where a crate will spare your dog many problems, so she needs to feel at ease in a crate.
It will never again be as easy for your dog to learn to rest calmly in a crate as in puppy hood. At the same time, the crate helps your puppy develop bowel and bladder control (which is not complete until at least 4 months of age and could be longer in a Bichon, even with the help of a crate) and avoid forming bad habits that are difficult to change. The use of a crate can spare you and your dog much unpleasantness.
To house train a puppy you need 100% supervision. The puppy needs to be in the room with you as much as possible -- never loose in the house until much later. If you see the puppy start to have an accident, you don't punish or yell. You scoop the puppy up and rush her outside, in the hopes of getting her to finish there. You praise her for relieving herself in this proper place.
Start out house training by going out WITH the puppy about once per hour, when you are at home and awake. As she progresses and you get to know her better you can decide how often she needs to go, and eventually you can watch her from the door if you have a fenced yard. Don't leave her outside alone -- it isn't good house training and lots of bad things happen to dogs alone outside, especially cute little ones.
Unless you must leave your puppy alone for long hours it is not a good idea to use any method that involves teaching the dog to relieve herself in the house. It can confuse her and make complete house training take longer. Sometimes this problem is unavoidable if people have to be gone to work when puppies are young.
If you find an accident after the fact, oops, it's not the puppy's fault, it's the owner's fault! You weren't watching the puppy well enough. Never punish for housebreaking accidents. That can create much worse problems, such as a puppy who won't relieve in front of you at all, a puppy who gets defensive out of fear of punishment and starts snapping at people, or a puppy who starts submissively urinating.
Any accidents need to be thoroughly deodorized with either white vinegar (only works while the spot is still wet) or a bacterial enzyme odor eliminator product such as Nature's Miracle. This will neutralize the odor to your nose, but more importantly, to the puppy's much more sensitive nose. If you don't do this properly the scent of past mistakes will signal the dog to come back and use that spot again.
When you cannot watch your puppy she needs to be in her safe place where she can't make mistakes, and the crate is an excellent choice for this place. Put the crate in your bedroom at night, and be careful not to let her out of the crate when she is in the act of making noise so she will learn to be quiet in there. If you plan to allow her on the bed, don't do it until she is older.
After house training many people start leaving their puppies out of the crate and loose in the house, then are horrified at the chewing that starts after the permanent teeth erupt and have to be set in the jaw by the dog chewing. A Bichon is not likely to be a major chewer, but there will probably be some mischief. At this point the crate is still a great safe haven to protect both your things and your dog.
Look for a puppy kindergarten class in your area and arrange to take your puppy when she reaches the correct age. This can make a big difference as she matures, and the opportunity for it is over by the age of 6 months. Obedience clubs often have these classes, and you can find these clubs listed by state at www.akc.org.
Make sure young children are never allowed to treat your puppy in any way that could cause her to feel pain or fear. Try to look at it from the puppies point of view, and interrupt any such behavior from the kids whether the puppy complains or not. It is common for dogs to tolerate this for a long time, then suddenly defend themselves when they just can't take it any more.
