I sorry to tell you that the marking usually doesn't stop even if they are neutered after they are sexually mature, although it may get somewhat less. My daughters dog was 1 year when he was neutered and he did slow down some but belly bands are the answer to your problem. Unfortunely I have Chance here every day while my daughter works and hos marking started my neutered male Max to start doing the same. They both wear belly bands in the house with maxi pads or poise pads wich I change every 3 hours or so. It's not ideal but is much better then cleaning up pee all the time. Hope this helps |
