I'm not an expert on male dogs, but I do know that when they are neutered that it is suppose to make them stop marking. But it is not a 100% guarantee that it will stop your dog from marking. I've read where people got their dog neutered, but it did not completely stop the marking, but it did help. Do a search on here for 'marking' and you will come up with a lot of threads on it. I've only been around female dogs. We just got our first male. He is 10 weeks old, so we will be going through this also.
