i think i might of heard of that before, but i'm not totally sure.
what type of dog is it, a small one, big one.
you'd be surprised how long they can hold it, i personally wouldn't use those puppy pads cuz that will kill everything you have worked at so far. use a crate. once a dog learns to hold it they can hold it. i know at six months everything isn't fully developed yet, well bad term, but you know what i mean, but thats still a decent age, i mean its not like he's just 8 weeks old.
but even when they are young, they learn real quick with a crate, i always crate train because they will not go where they have to sleep. for the most part that is, i mean if they had diareah or something.. okay, then they will go...
bear was put in the crate the first night i got him, and i don't remember him ever having an accident in there. i'm not saying i left him for hourrs and hours, but just pointing out that they do learn very quick when crate trained.
