schnauzer urinating

Question
Karen
 I have two miniature schnauzers
one male and one female both about four years
old. I had the female spayed a couple of years
ago.

My question is , the male who has never been
a problem for three years , has been urinating
in the house for the past year and even though
I had him neutered it is still a problem.

  Any advise appreciated  

Answer
First, since schnauzers are prone to urinary problems, I would have him checked by your veterinarian to make sure that he does not have a bladder infection or a problem with bladder stones.

If he is healthy, you may not ever be able to break him of marking in the house since he has been doing it for so long now. Clean all those areas thoroughly and try going back to basic crate training just as if you had brought in a new puppy. The best solution might be to simply use a belly band on him: http://www.showpaps.com/bellybands.html
