bad habits

Question
My dog is 10 months old and was well house trained but over the past 6 weeks he has taken to urinating in the house all the time, we have tried many things to stop this behaviour but nothing seems to work.

Answer
First if he hasn't been altered,getting him done my correct the problem

Second this might be a medical problem,most likely a blader infection which is common

Now,if he's already fixed,and a blader infection has been ruled out by the vet-the next thing you can do is to use a crate,andkeep him in there at all times,except to go outside,to play with him to feed him,take him places ect and do that for about three weeks then slowly let him out more
