Take a deep breath, it will get better :smile: I don't usually recommend them but maybe in this case some puppy pads would be the go. That way you can at least keep training him to go in the one spot rather than everywhere and then move them to outside when he is allowed outside again.
The trick with toilet training is to ALWAYS and I mean ALWAYS make sure he toilets in he spot you have chosen for him. He doesn't get a choice, cause if he is out with you you are watching him like a hawk and taking him to where he needs to toilet before he has an accident.
This is straight after every meal, immediately upon him waking up and every 30 minutes (cause he is not well and probably can't hold for long) to 1 hour in between. If you are not watching him he should be in his crate, that's after you have made sure he has toileted and isn't going to be forced to make a mistake in his crate. If the crate is the right size eg. not to big, doesn't have food or water in there and the pup isn't left so long he can't hold it he won't make a mess in his crate.
I have read this somewhere before and think Wonderpup put a better version up in another thread - but basically if you puppy has an accident, roll up a big heavy newspaper, stand in front of the pup and whack yourself three times really hard cause YOU allowed the pup to toilet in the wrong spot :rofl: I can't stress this enough, you are the human, you are responsible for helping the puppy to toilet in the right spot EVERY TIME. Not every second or third time or when he accidently gets it right - EVERY TIME. Be his friend and help him get it right.
OK as you can tell I love toilet training :smile: Hope it helps some.
