In addition to training, make sure that the areas where he is going to the bathroom are cleaned thoroughly. Enzyme cleaners work best..."Nature's Miracle" is really good. He is smelling where he has marked and thinks that it is ok to go there.
I think I'm worn out of all the potty training post I've been doing lately..lol..okay, one more..(sorry for everyone that keeps having to read it) First, you should crate train the puppy. Which means, anytime you can't keep on eye on him, or at night, the dog should be in a crate. If he whines, you have to ignore it. By letting him out, he learns that whining means getting his way and he will use this in other aspects of his life. A puppy shouldn't be in a crate longer than their age. If they are 2 months, 2 hours. 3 months, 3 hours. (That's as long as they are able to hold it.) I never leave mine in his crate longer than 45 minutes except at night. I personally dont think any dog, regardless of age should be in a crate longer than 4 hours. Second, I would totally start over. Take the puppy out every half an hour to go potty. When you take him out, you HAVE to go out with him. Say, 'go outside!' in a really excited/happy voice. Once outside, say 'go potty' over and over. It's important that you say this EVERYTIME you go outside. He will soon learn that this term means to go potty and will go on command. When he goes, praise him like crazy. You could also give him treats. But it's important to give the treats outside. If you do it once you're back in, he will think he gets treats for coming in the door, not going potty. It's also important not to praise him or talk until he is completely done. If you do, then he will just go in the house in like 15 minutes because he didn't finish the first time. If he doesn't go, you put him in his crate. You don't say 'no' or anything, you just take him right to his crate. Leave him there for 15 minutes. Then repeat the process. If he doesn't go, back in the crate. Eventually he will learn to associate going potty with getting to be out, and will go everytime you take him out. If you cannot keep an eye on him every second (and I mean every second, even if you're on the phone) he should be in his crate. If you would prefer, put him on a leash and attach the leash to your pants so he has to stay by your side when he is in the house. A dog should never have free run of the house until they are completely potty trained. When he has an accident, don't hit him or rub his nose in it. Say 'NO!' loudly if you catch him and immediately take him outside. It's important to stay consistent and do this everytime. When he goes outside, praise him. If he won't, in the crate again. If you don't catch him in the act, you can't punish him. He won't make the distinction. With my dog, if I caught him in the act, I did swat at his butt to scare him. It was kinda like the motion you make to get a fly off someone. You need to take him out after he eats, after he plays and after he wakes up. My dog will go potty, and then play with the cat, and literally have to pee again 15 minutes later from playing, so watch him whenever he is running around. It takes a lot of patience. Some dogs get it in a few days, some months. The important thing is to praise EVERYTIME he goes. Dogs love positive reinforcement. I used this technique and it took 2 weeks. Good luck! Welcome to the board! Sorry this is such a novel. :o)
You obviously didn't train him/her enough. Get a crate, put him/her in it when your not watching him/her. ONLY scold him/her if you see him/her doing it, and don't scold em 5 minutes later, do it right away, then take your pup outside. Take him/her outside every hour during the day and early in the morning. Keep in a crate at night. I'm 13 too, and it took me a week to housebreak Shadow.
aisha, lol, I was thinking of that when I was typing it..hehe...yeah, gonna do that from now on. The thing about potty training, is there is so much stuff you need to make sure you do consistently. I remember when I got my chihuahua, all I was told was, "Take her to the puppy pads oftan to get her to go there". I didn't know about the pet enzyme cleaner for her accidents, or that I shouldn't let her run free in the house unsupervised..I'm surprised she got litter trained..lol
