When I have such a young pup, my main goal is preventing accidents. It would be very unusual for a puppy this young to tell you she needs to go- she probably doesn't know herself until it is almost too late
There are two techniques that help a lot with such young puppies-
umbilical cord training and
the puppy airlift.
"Umbilical Cord Training is a housebreaking method that's pretty much what it sounds like... your dog is attached to you with a cord (his leash) throughout the day. It is a supervision-based program that requires vigilance but yields excellent results with just about every dog or puppy. This method works well in conjunction with other methods, such as crate training or indoor potty training. It is also an excellent alternative for those who spend a lot of time at home and prefer not to use a confinement method like crate training."
Puppy Airlift
"...he's very likely to try to go potty any time his feet touch the ground. So, for the first few days, you might want to try having his feet touch the ground in his potty area only. We want his feet on the ground only in areas where it's okay for him to pee and poo. If you're teaching Fido to go potty outside, you can play with him and let him walk around outside only."
Either of these two methods might work well with your puppy. The puppy airlift is extremely effective (very few pups will pee on their owners :lol-sign
but only works with fairly young, small puppies. As they get older it ends up being too much restriction and they don't like being carried anymore. Umbilical cord training isn't as effective at completely stopping accidents, but, most puppies don't want to pee right next to you and where you both are sitting. They prefer to wander off a bit before they potty, so it does create a little inhibition. The main benefit is that you will be really vigiliant about watching and your pup won't be able to learn to sneak off and potty.
Accidents are not such a bad thing if you see them as they are happening and stop the puppy. But, uninterrupted accidents are terrible! Pottying is inherently rewarding (imagine the relief you feel when you empty your bladder), so you do not want to let any accidents get by you in the beginning. Good luck and have fun with your new baby!
