Hi there! I have 2 sheltie puppies myself. They are 8 months and 5.5 months now. (We'd love to see pictures of your little one!) With my first puppy, I took him home at 10 weeks as well. A 10 week old puppy is the equivalent of a child of about 1 year of age, more or less. You cannot EXPECT a 1 year old child to understand "what you want". And spanking will only cause fear. A dog should never obey out of fear, same as a child. They should obey because they want to, either out of their will to please or because of a positive outcome such as food. Your puppy is only just starting to develop the muscles to hold in its own waste, it's going to take a lot of patience to achieve what you're asking for here.
That being said, I don't really think there is any way for your 2 year old and a very young puppy to "play" safely. If I were you, I would have waited to get a puppy for a few more years. But it is what it is. An ex pen is a MUST for your situation. I think that the only interaction that should happen right now between your son and the puppy is after the puppy has had a good bout of exercise and is about to go down for a nap. He can pet the puppy if the puppy is holding still. But I know how 2 year olds can be and it's VERY difficult to get a toddler to understand that a puppy is not a toy and can be hurt, scared easily, etc. A 2 year old petting a puppy usually looks more like a slap...and with those hand movements, it looks more like the universal play invitation for puppies which is the extended arm that slaps down onto the ground. So it's probably going to be more difficult for the puppy to understand what your son is trying to do.
A toddler also tends to wobble around and walk and act like an injured animal. This is irresistible for all dogs. Your puppy is mimicking the wolf bringing down the deer.
As for the biting behavior in itself, it may be partly due to lack of sleep. He's not going to be teething for a while, so it's not teething that is making him bitey. A puppy at this age needs TONS of sleep. Playtime should only last for about 20-30 minutes before it goes potty and then has another nap. Lack of sleep can lead to behavior problems in puppies.
To solve the biting problem, you must correct the behavior as it happens to YOU, not your son. Engage in play with the puppy, as soon as the puppy tries to mouth you, I would use a sharp "EH EH" (which seems to work better for me than a more even-toned "No"). When this happens, stop play entirely for several seconds. Begin play again, and repeat this process. No matter how frustrated you get, please, under no circumstances hit or shout at the puppy. This serves no purpose except for you to vent your own anger. You should never correct any animal out of anger-only as part of training. The crate should not be used as a disciplinary measure, either. The crate should only be a happy place where your puppy receives his meals, warm blankets, chew toys, and is a safe haven in times of discomfort or fear.
In the meantime, once you are able to stop the mouthing of your hands, etc, I would encourage the puppy to chase after balls, ropes, etc, and then introduce your son into the mix having him throw things for the puppy to chase. While you are playing with the puppy, have your son watch the way you do it. I know, it's going to be irresistible to him not to be able to run around with it, but things need to be looked at from a safety standpoint...the puppy can hurt your son, and your son could hurt the puppy-especially if he gets frustrated from being scratched up. I wish you the best of luck, and training classes will definitely help you learn more about dog behavior and how to control any problems that arise. Hope this helps!
