@EmzBPupMum Same age and same issue for us. He knows to go outside, today he rang the bell to have a wee twice, plus I took him out a couple of times (after food, after he woke up) asked him to wee and he did. He 100% knows. This afternoon at 415 he asked to go out for a wee, then again at 455. He then wee'd on the floor inside at 515, 545 and 7pm. I don't even know how this is possible, they weren't small wees at all. He is a tiny 5kg dog but he is able to hold wees for several hours in the day and 8-10 hrs at night.
We just can't figure it out, during the day he'll go every 3-4 hrs then once DH and the kids are around it all goes crazy. It seems that if I am not devoting my time to him he just wees indoors, he also does it if I leave the room, it's like he squeezes out a little wee in protest.
It is not always as bad as tonight but pretty much every evening he will wee indoors, it is always 20-60mins after a previous wee. Short of being outside every 15 mins I am not sure what to do. I don't even think that'll help as he knows full well what to do.
I would love to know how to fix it. It's never poos, he's always been spot on with them outside. We thought we'd cracked it as he was doing so well, then it regressed then we thought we'd cracked it again and this week it's worse. If he was weeing that often all day I would suspect a medical issue but I don't think it can be.
