Okay, 1st: breathe in serenity..... Breathe out all those negative feels of fustration and hopelessness. Breathe in and out a few more times........., Ok, much better!
The first thing you need to get is a pet urine neutralizer like Simple Solution. You will need to use this to clean up the areas he pees on, so that there is no scent of urine in those spots, at all. Just cleaning them in the washing machine or using a regular detergent will not get the smells off. Puppies and dogs are attracted to previously soiled areas. It stimulates them and makes them pee, so it is very very important that you neutralize the area very well.
2nd - you need to keep your puppy confined in the area that you are in and only in that area and you need to be watching him every second. You cannot take your eyes off him for one second. If you cannot attend to him then you need to assign this to another person in the household (your husband) while you are busy or x-pen or crate him. No more free range of the household.
Another option is to tether him to you so that he stays with you at all times so that you can keep your ever vigiliant eye on him. When you see him look like he is going to go, then you need to walk him to the desigated pee area and wait with him for him to go.
Puppies develop all kinds of bad habits, one of them is to climb on the furniture. If he cannot be trusted up on the furniture (because he urinates on the furniture) then it is your responsibility to train him NOT to get on the furniture. He won't train himself so you have to take an active part in making sure he learns the accepted behaviors like: stay off the furniture; and develops good behaviors and manners. You can't teach them soon enough. To let the behavior continue, will make it harder for you to potty train him.
Is your little boy neutered yet? are you planning on it? I would recommend it.
How often are you taking him to his potty area? you should be taking him every hour on the hour or 1 and 1/2 hour depending on his peeing habits. This also is your responsilbility. He should never be allowed an opportunity to have an accident. You should avoid the accidents by keeping watch over him, keep him confined to one area and taking him out as often as he needs to, in the begining.
Very important lesson: DO NOT expect him to know how to ask to go to his potty area before he is 6-7 months old and it may take longer. You are going to have to be trained before he is. AND you cannot let up until he his reliably house broken. This will be harder work than you could possibly have anticipated, but it is the most necessary way to do it.
Your puppy only gets more access to the house, the more reliably he becomes. You have to introduce each room as if he was never potty trained before because each room is a new situation and your puppy has not been trained to NOT GO in that room. You work on every room, individually until he
learns=
you have trained him potty is only in the designated area, whether it be outside on on pads.
This is my advise to you. It has been proven to work 100%. REMEMBER: If your puppy is not housebroken, it's your fault not his. If he is not behaving the way you want, it's your fault not his. If he is regressing it's your fault not his.
I am not trying to be harsh, I just want you to understand that you should be more frustrated with yourself and not him, if things are not going as you feel they should.
