My brother has a male Yorkie who is almost two years old. He's adorable, shy, quiet. The problem is he marks indoors.\n \nLuckily, he is very short. When he marks, he hits the floor rather than furniture. However, it's a terrible habit. Has anyone had any luck getting a male dog to stop marking indoors?\n \nWhenever he comes over, we close all the doors and try to confine him to one area of the house. We try to stop him as he does it. However, we almost always find a couple of small spots after he leaves.\n \nAny suggestions would be great.
