@GloPro Thanks for your question :)
Firstly, at 11 weeks it’s really important not to expect too much too soon. The bladder is not strong enough at that stage to always get it right. I usually tell my customers to expect accidents until they are at least 8 months old.
It is really important that you do not tell soda off for having an accident indoors. If you do this it can cause them to be anxious when going to the toilet especially when you are around and, as a result, cause them to ‘hide’ their toileting (often in inappropriate places). On the flip side, give massive praise when he does go outside so he starts to recognise that he gets no attention for going inside but loads of good attention for going outside (obviously wait until he has finished his business before showering with praise). If you are clicker training, click as soon as he has finished.
I would also have a word that you use when you go outside to encourage him to go to the toilet. I know people that use “be clean”, “toilets” or, my personally favourite “wee wees” (I don’t use that myself but it makes me laugh whenever I hear it!!). To begin with, introduce the word after he has been but before you reward so he can start to associate the word with the behaviour with the reward. Eventually you will be able to use the word and he will know that when he heard it, he should try and do something. I know this works for a lot if my colleagues and customers.
As for asking to go out, this will come when he is able to hold his bladder for longer and knows exactly where he is supposed to go. In the mean time, make sure you take him out after every sleep, play and meal and just wait it out until he does something. The more consistent you are with this, the quicker he will learn the appropriate behaviour. Sometimes you will have to wait for a long time, especially as he is still very intrigued by the outside world and it’s much more fun to sniff than to pee!!
Good luck, feel free to PM at any time if you need more help.
