I suggest crating. Especially with so many dogs. I'm not sure how you handle walks and such, but a lot of exercise is helpful. They might be too far into the habit of peeing, so you might try belly bands. Wow I can't imagine five dogs!! Good luck. Maybe you should have your entire house cleaned carpets and walls and sofas, just so their scent isn't on anything. Max marked before he was neutered, and the neutering stopped the marking so since they are already neutered I can't suggest anything.

Good luck!
