My puppy is now 5 months old and still not house trained. I bred him and i started house training the whole litter when they were 6 weeks old. WAtching them constantly for signs, after meals, when they woke up, after play. I have carried this on with my puppy but he still wees in the house without warning. He sits for a fuss then he will just go, he knows it's wrong because he runs out of the room to the backdoor. I have always praised him for going outside and putting him outside when i catch him indoors.

Why has he not learned yet? He doesn't give warning so i don't know when he needs to go. I still put him outside alot and he always goes and then i praise him. Has he got a weak bladder? I would have thought by now he would be able to control his bladder, i haven't had problems before with house training.

Any advice would be greatly appreciated.

He doesn't know what he's done is wrong, what he knows is that when you stand up/do what you do when he's done it, you're not happy with him - are you perhaps mistaking submissive weeing when you fuss him, with urination?

I didn't realise that. It's definately not submissive weeing he doesn't do it all the time when being fussed. He just toilets with no warning. Should i just persevere with what im doing and hope he gets it in the end?

All i can say is take him out every hour if you can even with or without a sign. Cut his water off 2-3 hours before bedtime if he's going at night. Be consistant i've heard of stories about 3 year old dogs still constantly going in the house but you must stay consistant, you are doing the right thing by correcting him when you catch and praising him for going outside. Good Luck!

Please never restrict water especially for puppies who dehydrate all too easily and particularly if fed a dry diet.  Thirst is a horrible sensation anyway and not likely to help a dog settle at night so counter productive really.

Not only is water essential for bodily processes, it is also essential for the brain to function correctly in sleep - proper hydration means good sleep - a thirsty puppy (or human) won't sleep as well.

No, water should be available at all times; this is especially vital if feeding dry complete food (it even stresses this in the feeding instructions) and in hot weather. Extensive tests have shown that restricting children's drinks in the evening has no effect on whether they wet the bed, so there's no reason to believe that puppies will be any different. Water should be available to a dog 24/7.
