Yes, as Biz notes, mixed-use resorts where there are other ownerships interests other than WMtC's ownership, you may see dogs. WM Seventh Mountain is one of those resorts, where there are fractional owners whose units have different rules regarding rules.
But in terms of pets (not service animals), they are not allowed in WM units under the Declaration. So not even the BoD could make a change to allow them.
