I have both nutered and not - one maletse mix and one lab(lab not) and I have had no issues but I know that the smaller the dog the harder to train for marking. I agree - you can always use belly bands on them when they are inside - just incase.
Not to push myself but i - along with several others make belly bands. My discount is 10% just put YT10 in at checkout.
Keep us posted on what you do - Do what you feel best with. *hugs*
