What I did with my mim pin was I took him out every 2 hours day and night and the middle of the night. Plus he only got 1/4 of a cup of dry dog food in the morning and 1/4 at night. When they wake up from a nap u automatically take them outside to show them that's where their potty is and wait until they are both done peeing and pooping. Also at bed time u need to crate them because they will not go to the bathroom in their kennel. When u wake up in the morning u take then out eight away until they go to the bathroom. After they arw done feeding and drinking water they need to be taken out as well so they get use to their potty it took my min pin a month and he was potty trained and he is also trained off leash. Make sure u get up in the middle of the night every 2 hours to take them out and I guarantee they will be house broken in a month. If there is an accident in the house u take them over to the spot and show them that was naughty and put them in their kennel only the bad puppy though. If u catch either one going to the bathroom in the house u stop them instantly with a loud noise and take them outside asap. And that should do it. After meals and drinking take them out and get up every 2 hours to take them out. If u see them sniffing around take them out or if they are going around in a circle take them out quickly because otherwise they will poop in the house if your can do that they should be potty trained in a month to a month and a half. Let me know how it is working for you.
First, do NOT reply on simply crating them thinking they will not soil their crates. A 9 week old puppy is not able to hold it all night and when left with no option WILL soil their kennel. Leaving them all noght and expecting them not to go is NOT a proper kennel training method.
ALSO....correcting them for accidents ONLY works when they are caught in the act! Then you can give them a firm NO and take them out immediately followed with toms of praise if they finish out there. You do not punish them for a potty spot that you did not catch them making...by this time the point is lost and they do not understand.
DO NOT use the crate as your punishment for them, this will only cause them to dislike and be fearful of their crate. The less they think of it as a 'good' place the less they will want to go in and the less they will desire not to soil it.
Life isn't about waiting for the storm to pass. It is about learning to dance in the rain.
