Kathy,
Your best bet is to put a lot of research into where you are going to get your Malamute puppy from. If you pick the right breeder then they will be there to help you with any and every question you may have.
Our puppy came with a binder jam packed with every bit of information on Malamutes you could possibly hope to find - covering things such as training, feeding, grooming and so much other stuff.
When you take your puppy home the breeder will(or should) fully inform you about when they need to get their next vacination, worming medication etc. They should also be able to discuss with you what is the best age for neutering. Any responsible breeder who is selling a limited register puppy will probably have a spay/neuter clause as part of their contract.
