Unlike children who will insist on having a mind of their own, dogs are generally programmed to want to please their pack leader, which is you. (Unless you get something like a husky or a ridgeback, in which case you'll have a bit of a battle convincing them that you're the pack leader. Seriously, don't get one of those unless you really know what you're doing with training dogs.) Once you've established the pecking order, there's very little negative reinforcement required.
A few tips I've learned from having dogs:
- Dogs have incredibly short memories. Telling them off for something they did ten minutes ago is at best pointless and at worst counterproductive, because they won't associate what they did with the punishment. You can only punish a dog as it is doing the thing you don't want it to.
- Dogs don't really do shame. I get very annoyed by people who say that they trained their dogs not to excrement in the house by rubbing its nose in it's mess. The dog has no clue what that means, it only knows that you're being a queynte to it. House training is incredibly easy and requires absolutely no negative reinforcement, the puppy wants to please and if it knows that it's going to get a treat for shitting outside when it was going to excrement anyway, happy days. You stop treating them for it very quickly, but they've already made the mental association of shitting outside=good and it never goes away.
- Use a crate, and use it properly. Crates are not for punishment, ever. The puppy will quickly learn to love his crate, it's his space that no-one else can go in where he's safe from the world to sleep. And he won't mess where he sleeps, so it's a fantastic tool for training him to last through the night. Speaking of which......
- .....when it comes to puppy bladders, one month = one hour. The muscles that control the bladder are still developing, for each month he has been alive he can hold his bladder for an hour while he's sleeping. That means that if you get your pup at eight weeks old (and you shouldn't take them away from their mother any earlier than that), you'll be getting up every two hours to start with to take him outside to pee.
Good luck. Dogs are all kinds of awesome. This one's mine at six weeks old:
