How many hours should a 3 month old puppy sleep?

Puppy training is continual. You should set aside thirty minutes to an hour to work with the puppy on specific things, but you have to reinforce the behavior you are teaching the puppy all the time. You need to reward the puppy when it does what you want it to (ie, treats, playing with the puppy) and scold it when it does something bad (ie saying no, bad,).
