Cheer up,
I have a 7 month old lurcher pup, and he is STILL not housetrained. I do know why though, and it is mostly down to the fact that he sleeps in my kitchen, and doesnt get the idea that you go before bed time, and not in the night!
Also, he is very scared to go into the garden at night, as my dogs have suffered several attacks in the dark by a neighbours GSD cross! So i dont blame him!
Still, it is VERY upsetting when what you thought would be fun, turns out to be misery.
I can only echo what the others have said, DONT pay too much attention to how well other peoples dogs are doing, they are not your dogs, nor are they in your house, adn lets face it, there are not many people who will admit that a pup is not clean in the house!!!!!!
Apart from food (where all i can say is feed raw, i do, its great!!!!!!!!!!), is it possible that you are paying your pup TOO MUCH attention?
Puppies at 12 weeks get tired very very quickly, and need a lot of sleep, in short bursts usually. On the one hand, you dont want to be leaving the pup too long on its own, but there again, if you are paying it attention all the time, day in day out, it will both come to expect it, and also not be all that interested in you as a source of fun, and reward!
Have you crate trained her?
Not all puppies take to it, but most do (not my irritating lurcher pup though, any one want him, going spare!!!). Pick a crate that is not too big, it should be big enough to let the pup lie down comfortably, and turn around, sit and stand. But, if it is too big, then the pup can also poop in it, and you want to avoid that!
Then, once you have made the den a safe, and cosy place to be fed, and sleep in, you can use it when you cant watch the pup, or want it to have some alone time (very important, unless you want the pup to need you with it 24/7 for the rest of its life!!!).
This time alone, in a crate is great. As long as the pup is not left so long that it is forced to toilet in there, then that will be the one place it will hang on in!
Then, after every game, feed, sleep, crate time, let the pup out into the garden. But, only for a few minutes. If it goes, praise and treat, along with the word you want to use to ask it to perform later on in life. If not, back in the crate for a little longer, or keep a very close eye on it.
Another good tip, is to clean the areas the pup has accidentally soiled inside the house, with washing powder, NOT ammonia based cleaning products, as these will attract her back to that spot.
also, if she does mess in the house, transfer that mess to the spot outside that you want her to use, and leave it there for a couple of days, that should attract her to that spot.
You can start other kinds of training this young, i use the clicker training method, and it has worked briliantly with stubborn lurcher puplet Dill. I hate to brag, but at just 8 weeks (i did have him from 6 weeks old) he had an excellent sit! all using clicker training.
Just remember, only do a few minutes training a couple of times a day, they do learn much faster at this age, but also, brain exercise is as tiring as physical exercise!!!!!!
Good luck, but mostly, dont panic, it will happen, just dont stress out about it!
