I would get him neutered as soon as possible. That may help and may even put a stop to it altogether. My Ben only started to mark after he sired a second litter of puppies. He was almost 3 years old before he started marking! Most are more like your little man and start to mark at 5-6 months. Ben was a late bloomer. I think for him it was the combination of getting to act like a man and having the to smell the puppies little accidents in the house. No matter that I cleaned them immediately, he could still smell they had been there so he would mark to show his dominance. Anyway..... had quite a time with him marking. Finally I bought a new baby girl who was too little to breed so I went ahead and had Ben neutered at 3 years old. He has pretty much stopped all marking unless another male comes around. When I take care of my son's male dog, Ben starts marking again. He has also still marked a couple of times when something strange has been brought into the house like a large Fedex or UPS package. Not sure if he smells someone else on the box or what, but I've learned I need to unpack and get rid of the box! Still, he is pretty good about things now.
My mom has a papillion that she did not neuter until almost a year old. He was starting to mark and he really has never stopped. He marks the corner of her chair and the corner of her bed all the time. She is having a difficult time with this. I think marking is involuntary so you really cannot train it out of them. It is something they just have to work through on their own time and some never do.
The very best thing is to neuter them BEFORE they start to mark. That is the best chance of never having a marking dog. But that ship has sailed so the best you can do is get his procedure scheduled as soon as possible and hope he is more like my Ben who pretty much stopped marking when he got neutered. But be aware that another male dog even in the vicinity may start the marking again. |
