At 3 years old I think it would be hard to get him to stop even with him being neutered now, as he has formed a very strong habit. But neutering him would be your best chance. It would also be beneficial for his health and lower his risks for many health issues such as certain cancers...
The marking is one reasons to get them neutered before a year, after that it is really hard if not impossible to stop the marking especially if they are bred. A belly band would most likely, as already suggested would certainly help to save your house. |
