my male was neutered at 3 months by the breeder. He started lifting his leg outside at about 7 months but has never marked in the house. He is the last in a long line of male dogs that I have owned,all neutered between 3-6 months, and not one has ever lifted his leg in the house. I think I'd go nuts. I think it helps when they are outside trained, too. That's where they go and that's where they mark. |
