Will neutering my adult dog stop his marking behaviour?

[pingulingo]

I've a 4 yr old shitzu male. He's going to be neutered this month. He drives me bonkers when he is outside. He wants to mark every lamppost, tree, bush, corner going. Even in his own back garden. Will neutering help reduce this behaviour or have I left it too late?

Maybe it works for some dogs, I can only speak for mine and it didn't help at all. He was neutered at 2.5 yrs eight months ago. Still marking as before, if I let him, but has finally learnt that when I say heel he has to keep walking. He hardly ever pees in the garden, prefers to save it up for walks.
The only thing that neutering put a stop to was the constant sniffing the ground and trying to track down females in season. This started a week before he was neutered when he met a female lab in season and became obsessed.

Hasn't worked on my dog either, he even tries when he's empty !!

Yes, its funny to watch. Mine goes through all the motions, leg up at a precise angle, carefully aims at a specific blade of grass and nothing comes out

Yeah mine tries to do it on an empty tank too. But then I'm amazed he manages to go so many times before he finally runs out! Oh well, I won't hold my breath for it making any difference then!

My male boxer never goes to the toilet when he's out on his lead but there's two spots on the walk where he occassionally does the fake marking, he can go weeks and not do it then do it two/three days in a row.

Bassett hound and mix breed parasitically stopped overnight when neutered but they were both 6 months old, he is older so behavior will be more entrenched perhaps.
