954 Hi Dave,
It sounds like the normal type of territorial marketing I might encounter in a kennel situation where the dogs live on the same property but are not necessarily integrated with each other. It can cause a reasonable amount of insecurity and conflict over territory and/or social standing with the other dogs.
I personally would put this in the “management” category because it may be easier to “manage” than try to fight mother nature unless for some reason you wanted to integrate all these dogs which sounds like it would be even a more difficult situation.
