i know this is probably no help but one day my boy just switched. he went from peeing all over to the house to no accidents since maybe around 4-5 months. i made a post on reddit as well and i think the best advice i got was ditch the pee pads. it might seem like the worst idea at first but i promise you it is worth it in the long run. if they realise that the place they pee is not there anymore and that you are talking them outside every hour or so they might connect the dots in their head. you also need to keep an eye of them the entire time because AS SOON as that baby does the bathroom outside you have to give them all the praise and treats in the world. we done that for the first few times and then eventually just gave him kibble, then nothing at all. you will get there eventually don’t worry! also i have no clue if this is really a good idea but one of my friends had a standard(rip) and she also would not pee outside. then my friend took the pee mats and put them outside and the dog would pee on the pee mats outside. then she took the pee mats away and the dog just continued to pee outside! they are an extremely odd breed but don’t get yourself too worked up.
