Dog won’t stop weeing indoors

Hiya everyone,

Just after some advice. My 3 year old dog, who we've had since a puppy, will not stop weeing in the house. It has actually gotten worse in the last year, before that it was occasional but now it's every day.

He can happily go all night in his crate without weeing but outside his crate, he cant seem to differentiate outside from inside when he wees. We have had him tested for any underlying problems and nothing came back.

We have a routine of putting him on his lead, taking him in to the garden and treating him every time he goes for a wee outside. At this point we don't know what to do….

If anyone has any experience with something similar, or any advice it would be greatly appreciated

Thanks
