I have an intact 10 month old GSP puppy that has started marking in the house. I suspect several places and have seen him do it once. He was corrected immediately, while he was doing it.

Will having him neutered stop the urge to mark ? I had planned on waiting until after hunting season, Jan 1 and 1 year of age to be neutered. BUT marking in the house can't be allowed or tolerated. If neutering will help I will have it done earlier.

Any other suggestions would be helpful too. He does not go in the house normally, only a couple 2-3 accidents when he was left too long (my fault). He does not really tell you when he wants to go out. He will just look at you, and if you go towards the door he will run to it. Otherwise he is very dominant over our 5 year old Golden, he has marked on people recently too.

After typing this and seeing it in writing I am  sure that neutering will help. I am going to call the vet this afternoon. I will read your responses and decide to go ahead or postpone it  later.

Thanks, Dan

YES, neuter will help!  However, think about all the unaltered males out there, that were trained not to mark!  It can be done!  Pretty much same as potty training, what I would do if I were you is keep the little guy close, leash him to yourself, so he can only be "this" far away from you at all times, if you don't  want  to do that, gate him in same room as you, so you are paying attention, and as he slowly surfs a wall or something you KNOW he's gonna whip his leg up on, just correct him on the spot and take him outside.  Get some communication going.  They say dogs never fully empty their bladders specifically FOR marking.  Make sure you clean where he's marked well, or he will just go right back to those spots and do it again.  It's really not that hard, if you are paying close attention, and if you can't, leash him to you.
